Public Security: Criminal Investigation Special Response Team

Best Seth Lowell Build Guide

Written by Phạm Ngọc Bảo Châu · Updated 6 Oct 2026

Playstyle Overview

Seth is an A-Rank Electric Defense Agent who supports Anomaly teams with very little field time. His Core Passive Protector gives him a shield based on his initial ATK when he uses EX Special Attack: Thunder Shield Rush - High Voltage; the Agent positioned before him also gets the shield when he brings them in via Quick Assist. Shielded Agents gain up to 100 Anomaly Proficiency.

His Additional Ability makes his Chain Attack and Electrified Finishing Move lower enemies' Anomaly Buildup RES to all attributes by 20% for 20s. Build ATK% for bigger shields and Energy Regen. His buffs are easy to maintain but only cover himself and one teammate, and his animations are on the slow side.

Best W-Engines

Peacekeeper - Specialized

ATK 624 · ATK% 25%

His signature and best option without question: ATK% for bigger shields, Energy Regen while shielded to use his EX Special Attack more often, and +36% Anomaly Buildup on EX Special Attacks and Assist Follow-Ups, which is valuable in Disorder teams.

Standard Blocking Technique ›

While Shielded, the equipper’s Energy Regen increases by 0.4/s. The Anomaly Buildup of EX Special Attacks/ Assist Follow-Ups increase by 36%.

*Stats shown are at Base level.

Spring Embrace

ATK 594 · ATK% 25%

A more support-oriented option: ATK% for his shields, and an Energy buff gained when hit that transfers to the next Agent on swap, fitting Seth's Quick Assist playstyle well.

Hot Spring Soup ›

Reduces DMG taken by 7.5%. When attacked, the equipper's Energy Generation Rate increases by 10% for 12s. When the equipper switches off-field, this buff will be transferred to the new on-field character with its duration refreshed. Passive effects of the same name do not stack.

*Stats are shown at base level

Bunny Band

ATK 594 · DEF 40%

Behind the top two because its ATK bonus only applies in combat while shielded and doesn't enlarge his shield (which uses initial ATK only), and its defensive stats don't scale with his kit.

Pet the Bunny ›

Increases Max HP by 8%. Increases the equipper's ATK by 10% when they are shielded.

*Stats are shown at base level

Original Transmorpher

ATK 594 · HP 25%

Mostly defensive stats that do little for Seth, but it grants temporary Impact after he is hit. Usable when your Defense W-Engine pool is limited.

Starlight Knight Flying Kick ›

Increases Max HP by 8%. When attacked, the equipper's Impact is increased by 10% for 12s.

*Stats are shown at base level

Best Drive Discs

Astral Voice

4-pc ›

2-piece:

ATK +10%

4-piece:

Whenever any squad member enters the field using a Quick Assist, all squad members gain 1 stack of Astral, up to a maximum of 3 stacks, and lasting 15s. Repeated triggers reset the duration. Each stack of Astral increases the DMG dealt by the character entering the field using a Quick Assist by 8%. Only one of this effect can be active at a time in the same squad.

Swing Jazz

2-pc ›

2-piece:

Energy Regen increases +20%

The best support set right now: its buff triggers off Quick Assists, which Seth creates often. At 2 stacks it matches 4-piece Swing Jazz, and at 3 stacks it pulls clearly ahead. 2-piece Swing Jazz adds Energy; Freedom Blues or Chaos Jazz also work.

Swing Jazz

4-pc ›

2-piece:

Energy Regen increases +20%

4-piece:

Launching a Chain Attack or Ultimate increases all squad members' DMG by 15% for 12s. Passive effects of the same name do not stack.

Hormone Punk

2-pc ›

2-piece:

ATK +10%

+15% team DMG after a Chain Attack or Ultimate, usually triggered by a Chain Attack right before the main burst during Stun. Good with direct DPS or Anomaly Agents that don't need Freedom Blues; 2-piece Hormone Punk adds ATK for his shield.

Proto Punk

4-pc ›

2-piece:

Increases Shield effect by 15%.

4-piece:

When any squad member triggers a Defensive Assist or Evasive Assist, all squad members deal 15% increased DMG, lasting 10s. Passive effects of the same name do not stack.

Swing Jazz

2-pc ›

2-piece:

Energy Regen increases +20%

15% bigger shields and +15% team DMG whenever someone uses a Defensive or Evasive Assist. A great alternative or complement when 4-piece Swing Jazz is already taken; 2-piece Hormone Punk is also a good choice.

Freedom Blues

4-pc ›

2-piece:

Anomaly Proficiency +30

4-piece:

When an EX Special Attack hits an enemy, reduce the target's Anomaly Buildup RES to the equipper's Attribute by 20% for 8s. This effect does not stack with others of the same attribute.

Swing Jazz

2-pc ›

2-piece:

Energy Regen increases +20%

For Shock or Disorder teams: his EX Special Attack further lowers Electric Anomaly Buildup RES. It overlaps somewhat with his Additional Ability, so use his EX before the team applies Shock. It usually loses to Swing Jazz unless another support already wears it.

Endgame Stats

ATK: 2600 – 3200+ (shield caps at 3750 initial ATK, but that's hard to reach)
HP: 11000+
DEF: 900+
Anomaly Proficiency: 200 – 300+ (optional)

Seth's shield scales with his initial ATK (combat buffs don't count), so stack ATK% on discs and substats; the shield caps at about 3750 initial ATK, though that's very hard to reach. An Energy Regen Disc 6 lets him use his EX Special Attack often; Anomaly Proficiency is optional.

Skill Priority

Core Skill
›Chain Attack
›Special Attack
›Assist
›Basic Attack
›Dodge

Level his Core Skill first to strengthen his shield and the Anomaly Proficiency he grants. His other skills mostly add damage and Daze, so they're not urgent: Chain Attack, Special Attack, then Assist (his Defensive Assist deals decent Daze). Basic Attack is only worth leveling at M6; Dodge comes last.

Best Teams for Seth Lowell

Most Used Teams Right Now

Jane

Yuzuha

Seth Lowell

The only Seth team recorded in the current Shiyu Defense, though its usage is very low. Jane shares his Public Security faction and unlocks his Additional Ability; his Anomaly RES shred and Anomaly Proficiency buff raise her Anomaly damage and help her cap her Core Passive bonus.

Anomaly Teams

Seth's shield adds Anomaly Proficiency, boosting the DPS's Anomaly damage. Place Seth right after your main Anomaly DPS, since his Quick Assist brings in the Agent before him. Vivian can be replaced by Burnice (off-field Burn) or Velina.

Seth and Yanagi share the Electric attribute and unlock each other's Additional Abilities, greatly boosting both their Anomaly Buildup; his Anomaly RES shred suits Yanagi's Anomaly and Disorder damage. Rina boosts the team's PEN Ratio.

F2P Team

Anby, an Electric Agent, unlocks Seth's Additional Ability and provides Stun; Billy is the DPS and lets both himself and Anby unlock their Additional Abilities.

Best Bangboo for Seth Lowell

In the Anomaly team with Vivian, use Robin (activated by a Mockingbird member), or Magnetiboo or Brawlerboo. With Yanagi and Rina, Plugboo shines thanks to two or more Electric Agents.

In the F2P team, Sumoboo adds Daze when a Stun Agent like Anby is present; Bagboo, Paperboo and Electroboo also work.

Mindscape Cinema

Which Mindscapes Are Worth It?

M1 is the most valuable upgrade for Seth's support role. M6 is also very strong since it turns him into a viable damage dealer, while M4 improves his Stun. M3 and M5 only add skill levels and are not counted.

M1
Shield value and its cap rise by 30%, and the Core Passive's Anomaly Proficiency bonus lasts 10s longer after the shield ends, clearly improving his support.
M2
He starts battle with 75% Resolve, and Basic Attack: Lightning Strike - Electrified builds 35% more Electric Anomaly, making Shock easier to apply. A decent upgrade.
M4
His Defensive Assist deals 25% more Daze, helping the team Stun enemies faster.
M6
The Finishing Move of Lightning Strike - Electrified deals extra damage equal to 500% of his ATK, always crits and gains +60% CRIT DMG, turning Seth into a real damage source.

HeroismRecommended

The shield value provided by Shield of Firm Resolve and its maximum limit is increased by 30%. When Shield of Firm Resolve ends, the Anomaly Proficiency increase provided by Core Passive: Protector lasts an additional 10s.

When it comes to team missions, Seth is always leading the charge.

"Let me handle the arrests! I scored a 99 in close-quarters arrests, and the only point deducted was because I accidentally sprained the instructor's wrist."

Recklessness of YouthRecommended

Upon entering battle, Seth immediately gains 75% Resolve. Hitting an enemy with Basic Attack: Lightning Strike - Electrified increases the move's accumulated Electric Anomaly Buildup by 35%.

Many criminals make the mistake of underestimating Seth.

It might be his pure, clear eyes or those innocent-looking furry ears and tail.

Whatever the reason, everyone who underestimates him eventually pays the price.

Slow Reflexes

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2

"A skilled officer like you must handle everything on your own, right? No help from others, surely?"

Even after hearing this, Seth remained composed and didn't say a word.

It wasn't until midnight that he suddenly woke up: "Could that guy's comment earlier... have been a dig at me?"

Core AspirationRecommended

The Daze caused by Defensive Assist: Thundershield is increased by 25%.

"Put aside your foolish notions of good and evil. You can't protect everyone. Sometimes, you have to make a choice."

"This is my choice, and it's the core responsibility of an officer — you're the one who has changed, Brother."

Distant Admiration

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2

Seth used to deeply admire and respect his older brother. But as you know, "admiration" is the furthest thing from "understanding."

"Someday, I'll become the finest officer... and make him eat his words!"

IdealistRecommended

When Seth lands a Finishing Move on an enemy with Basic Attack: Lightning Strike - Electrified, it deals additional damage equal to 500% of his ATK. The attack is guaranteed to trigger a critical hit, and CRIT DMG is increased by 60%.

To a young person, everything is clear-cut, with a stark contrast between black and white, right and wrong.

There will always be someone who tries to tell him that the world is a murky gray.

But is a world where everything is clear-cut and distinct really not worth striving for?

Story

Agent Profile: Seth Lowell

Seth, a rookie officer in the Public Security Criminal Investigation Special Response Team, is a key player in providing fire support during criminal investigations.

He graduated at the top of his class in the academy and could have landed a higher position, but he chose the tougher path of the Special Response Team.

His impressive profile makes him seem like a genius, but he's actually a hard worker who has had his own struggles. There have been times when he practiced the subjects he wasn't good at until he cried.

Seth is quite smart, but his personality often leads to him being taken advantage of by cunning criminals, or sometimes, coworkers (?).

The subject he's worst at is infiltration. Rumor has it that he holds the academy record for "fastest to get busted" in infiltration tasks.

Based on the video intel we have, he seems a bit slow to catch on.

For instance, when someone is being sarcastic, it takes him a long time to realize it.

Increase Trust to Close to unlock more

The profile shows that Seth has an older brother who holds a higher position in Public Security.

To some, Seth is a rookie riding on family connections within Public Security, but he got in on his own merit and has nothing to do with his brother's influence.

Currently, they are not on good terms. When they encounter each other at work, they pretend not to know one another.

Seth views his brother as a rival he must surpass, and is working hard to achieve that goal.

Cooperation Notes:

Belle

Seth really is a feline Thiren! He's like a kitty magnet.

Wise

I remember seeing him being completely surrounded by stray cats on the street once.

Must be nice to be so loved by cats.

Thiết Lập Nhân Vật 3

Sơ yếu lý lịch cho thấy Seth có một người anh trai cũng làm việc trong Cục Trị An và có cấp bậc khá cao. Trong mắt một số người có ý đồ xấu, Seth chính là đối tượng "COCC" trong hệ thống Cục Trị An. Nhưng trên thực tế, việc Seth được nhận vào Cục Trị An không liên quan gì đến anh trai anh ấy. Hiện tại, quan hệ giữa hai anh em rất kỳ lạ, ngay cả khi có đụng mặt trong Cục Trị An cũng sẽ vờ như không quen biết. Seth dường như đã đơn phương coi anh trai mình là kẻ địch trong tưởng tượng, và đang nỗ lực để chiến thắng anh ấy.
