Wind
Fudou Style Martial Arts
Performs up to 5 fisticuffs empowered by a mighty wind, dealing Anemo DMG.
Charged Attack
Consumes a certain amount of Stamina and performs a sweeping kick that deals Anemo DMG.
Plunging Attack
Calling upon the surging wind, Heizou plunges towards the ground from mid-air, damaging all opponents in his path. Deals AoE Anemo DMG upon impact with the ground.

Heartstopper Strike
Wields the swift winds to launch a Heartstopper Strike that deals Anemo DMG.
Hold
Charges energy to unleash an even stronger blow. He will obtain the Declension effect while charging, which will increase the power of the Heartstopper Strike. When the skill button is released or the skill finishes charging, he will strike forward, dealing Anemo DMG.
Declension
Increases the power of the next Heartstopper Strike. Max 4 stacks.
When you possess 4 Declension stacks, the Conviction effect will be produced, which will cause the next Heartstopper Strike to be even stronger and have a larger AoE.
This seemingly ordinary strike contains Heizou's desire for criminals to honestly confess and repent.

Windmuster Kick
When Vacuum Slugger hits opponents affected by Hydro/Pyro/Cryo/Electro, these opponents will be afflicted with Windmuster Iris. This Windmuster Iris will explode after a moment and dissipate, dealing AoE DMG of the corresponding aforementioned elemental type.
Vacuum Slugger can afflict a maximum of 4 opponents with the Windmuster Iris. A single opponent cannot be under the effect of Windmuster Irises of different elements at the same time.
A unique technique that gathers Anemo in one place before unleashing it all in one kick. Is always there in a pinch to land on some criminal's fleeing back.

Heizou (Quickswap DPS/Support) | Build
Character Guide • Build: Shikanoin Heizou | Update Date: 05/01/2023 | Editor: Samantha#9907
• Best Weapon(s):
Skyward Atlas is Heizou's general Best-in-Slot weapon for his personal damage owing to the large attack stats it supplies.
Sacrificial Fragments R3+ (DPS)
The additional skill charge, coupled with the additional swirls instances, composes a potent weapon that is comparable to other 5 star catalyst options — even when the added skill is left unstacked.
Widsith (DPS)
Since each buff the weapon passive provides works well on Heizou, Widsith — at high refinements — has the ability to be on-par with his 5 star options. However, owing to the 30s buff trigger cooldown, 5 star options still pull ahead when the note buffs are averaged.
Thrilling Tales of Dragon Slayers (Support)
Since the weapon passive limits the flexibility of rotations in order to utilise its strong single-character buff, players are encouraged to run this weapon only when playing an already rotation-strict team.
• Replacement Weapon(s):
A strong F2P weapon that is very competitive with the other 4 star options, in addition to having an easy to maintain weapon passive. For those without the liberty of catalyst options, using a billet to craft the Mappa Mare for Heizou is a solid course of action.
Solar Pearl (DPS)
A decent weapon with a passive that, as a whole, works well with Heizou's kit. However, it is not advisable to purchase the battle pass purely for the crit mainstat because Mappa Mare, at high refines, performs similarly while being a F2P option.
Prototype Amber (Support)
Prototype Amber has a unique passive that aids healer-less teams with micro-heals in addition to managing his ER requirements when Heizou can only manage to use one skill per burst. The value of the energy refund weapon passive greatly depends on if the player has his C4, which would provides a large reduction to his ER requirements.

4 Viridescent Venerer is the best artifact set by far for Heizou. In teams that already have an anemo running the 4-piece set or mono geo/ anemo team compositions, running 2-piece set combinations on Heizou is an option.
Heizou (On-Field EM Carry/Driver) | Build
Character Guide • Build: Shikanoin Heizou | Update Date: 08/14/2022 | Editor: Luno#1337
• Best Weapon(s):
A potent weapon option that shines best in electrocharge teams as it can buff both electro, and hydro party members. Given its strong multi-character buff, coupled with a much less rotation-restrictive trigger condition, makes this weapon an excellent choice for Heizou in monoelectro and electrocharge team compositions.
Sacrificial Fragments
Although not a weapon to support party members, the boost in personal damage and an additional charge of his skill will usually compensate for the lack of team buffs; particularly in teams where Heizou can proc many swirls and gain electrocharge ownership.
Thrilling Tales of Dragon Slayers
A low-investment option with a strong buff, albeit only for one team member. Since the weapon passive limits the flexibility of rotations in order to be optimally utilised, it is most advisable to run this weapon when playing an already rotation-strict team.
• Replacement Weapon(s):
For teams without healers, Prototype Amber can be a viable option with its small yet significant heals. At R5, the weapon drops his ER requirements by ~80%; enabling Heizou to either burst twice per rotation instead of once for some extra personal damage and additional CC, or to mend his ER needs in teams where Heizou can only feasibly get off 1 skill per burst. However, it is noted that the value of this weapon diminishes with his C4 as it already reduces ER requirements significantly.
Favonius Codex
When Heizou is in low particle teams or teams that would benefit from auxiliary particle generation, Favonius Codex is a great option to aid his teammates er requirements, notably when given the opportunity to proc the passive multiple times throughout the rotation. However, players must be able to afford the crit rate substats necessary in order to proc the passive consistently.

Namecard

Shikanoin Heizou: Temari
Namecard style. A Temari of entwining strings in various colors. It must have taken someone's great effort to make such an item, yet Heizou only sees it as a simple game to untangle each string.

DefaultShikanoin Heizou's outfit. Having taken his outer coat off and tucked it around his waist, the Tenryou Commission detective cuts quite the dashing figure.
Shikanoin Heizou is an extraordinary young detective. Though working at the Tenryou Commission, he is at odds with the usual impression of a public servant, who is expected to be "stern," "solemn"... and "solemn" again. On the outside, he appears more well-behaved and polite than any other new hires, but on the inside, he is actually thumbing his nose at all the official mumbo jumbo. Unlike his colleagues, he does not go to the Station to report for duty on a daily basis and rarely shows up for any routine patrols. It can seem like ages since you last saw him, and you may finally chance upon him at some crime scene. Yet, judging by that ever-present grin, you can hardly tell if he is actually there working. Funnily enough, all his "unorthodox behaviors as a public servant" are somewhat acquiesced to. His colleagues are more than willing to work with him and his boss seldom criticizes him for being this unfettered. Even his boss's boss inquires after him every now and then. All this can be safely chalked up to his unrivaled prowess as a detective. Whenever the Tenryou Commission is tackling an unusually complicated case, be it a major one or a mysterious one, everyone regards Heizou as their last hope to crack the code. Even the head of the Police Station marvels at his extensive experience in solving cases, but Heizou himself has a different opinion about that. "Experience is another name for people's past mistakes, and that's not my trump card." "My trump card is something I was born with."
The name's Shikanoin Heizou, sharpest and most successful detective of the Tenryou Commission... Ooh, my goodness, life's really put you through the wringer recently, hasn't it? I can tell. Here, why don't you take a seat, tell me the whole story.
