Look, let us be honest: the 'Seven Knights Re:BIRTH (hereafter SKRB) x Demon Slayer' collaboration hero 'Agatsuma Zenitsu (hereafter Zenitsu)' is currently getting a much warmer reception from players than his banner partner 'Kamado Tanjiro'. The secret behind this buzz? Well, Zenitsu comes fully equipped with the exact toolkit the SKRB arena is crying out for: 'Blessing', crowd control removal, and crowd control immunity. Some fans are even joking in the community that Zenitsu is looking far deadlier here than in the original source material. KookminTree has broken down just how lethal Zenitsu's kit actually is.

Q. What kind of hero is Zenitsu?
A. Zenitsu is a damage dealer who relies on crowd control debuff immunity and Blessing to dish out defense-ignoring pain.

Zenitsu is turning heads primarily due to the ridiculous utility of the passive skill 'Thunder Breathing'. Thanks to 'Blessing', incoming damage is capped so it never exceeds 25% of Zenitsu's maximum health in a single hit. Pile on a physical attack-scaling shield triggered whenever a debuff is cleansed at tier 2, plus an entirely separate attack-scaling shield at the start of combat, and you have a character that simply refuses to die.

Furthermore, whenever Zenitsu gets hit with pesky crowd control debuffs like 'Stun' or 'Sleep', those effects are instantly purged, granting 1 turn of crowd control immunity and 25 Awakening gauge. Since there is no cooldown or restriction on this cleanse during combat, Zenitsu essentially boasts permanent immunity to crowd control. To top it all off, the passive permanently grants allied attack-type heroes a 25% critical hit rate boost while slapping all enemies with a 34% effect resistance reduction.

Skill 1, 'Thunder Breathing First Form: Thunderclap and Flash', is Zenitsu's signature move from the original series. It deals 2-hit piercing and defense-ignoring damage to a single enemy while simultaneously stripping away 3 buffs. If this skill secures a kill, it chains into a consecutive activation with 100% potency, letting Zenitsu take down up to two targets in the blink of an eye.

Skill 2, 'Thunder Breathing First Form: Thunderclap and Flash - Sixfold', hits all enemies with 2 turns of turn-based buff reduction, a 29% defense drop lasting 3 turns, and 2-hit defense-ignoring damage. Once you hit tier 6, both Skill 1 and Skill 2 gain an additional 'Shock' effect on every strike, though the activation rates differ at 70% and 35% respectively. Even the basic attack carries a 30% chance to strip a buff, giving you a cheeky way to gamble away an opponent's 'Immortal' status.

The Awakening skill, 'Thunder Breathing Seventh Form: HinoKami Kagura'—adapting the devastating new Thunder Breathing technique Zenitsu whipped up in the movie to take down the fallen senior disciple Kaigaku—introduces an execution mechanic. It targets the two enemies with the highest attack power, making it a terrifying tool for sniping the opposing team's main carry. After landing two defense-ignoring strikes, any enemy left with 26% health or lower is instantly executed. Skill enhancement adds another 2 turns of buff reduction, and reaching tier 6 tacks on the Shock effect.

Q. What are Zenitsu's core buffs and debuffs?
A. Shock, turn-based buff reduction, Blessing, and crowd control immunity.

As mentioned earlier, Zenitsu's crowd control immunity is practically a permanent state of being. The game processes it in a neat loop: getting hit by a crowd control debuff, cleansing it instantly, and triggering 1 turn of crowd control immunity, meaning nasty surprises like Shock or Stun simply bounce right off. Couple that with the Blessing effect mitigating near-fatal hits, and the survivability speaks for itself. While the Shock effect requires reaching tier 6, it triggers on every skill outside of basic attacks and passives, making Zenitsu a match made in heaven when paired with 'Awakened Eileene', who boosts Shock application rates. Meanwhile, the turn-based buff reduction is packed into Skill 2 (2 turns) and the Awakening skill (2 turns).

Q. How should I set up Zenitsu's equipment?
A. Depending on your preferred stat options, either 'Seeker' or 'Assassin' sets are recommended.

Zenitsu's gear essentially boils down to a binary choice between the 'Seeker' and 'Assassin' sets. Seeker makes it easier to build weak point attack rates, while Assassin streamlines your critical hit rate. Since Zenitsu naturally gains an 18% critical hit rate at tier 4 and another 25% from the passive, hitting the 100% critical hit threshold is remarkably straightforward with either set. The 4-piece Seeker bonus grants a 35% boost to weak point attack damage, whereas the 4-piece Assassin bonus increases defense ignorance by 15%. Because Zenitsu's first skill, second skill, and Awakening skill all deal defense-ignoring damage, the Assassin set squeezes out just a tiny bit more efficiency from the kit. Just remember that if you do run the Assassin set, you will want to roll weak point attack rate as the main option on your weapons to make hitting 100% weak point rate a breeze.
