Hiya! Just want to write a brief note before the concept. I've been doing this for a while (writing down character concepts) and I figured maybe I could share and see what people think. I plan to post more, so I hope you guys enjoy these!

Given the Collab rerun a lot of people in my guild have been talking about alternative collabs, and of course, Demon Slayer comes up a lot. I saw an image someone had made a bit ago (before Re:Zero Collab was even close to being announced, also credit to u/kingfirejet on reddit and @BruLee_Arts (I assume that's a twitter handle)) and the Zenitsu in that image has been really inspiring to me for a while, so I figured I'd try my hand. 

Also, and my final little disclaimer, this might be a little broken. If you want to try to help me balance it, I welcome your advice, or if not, it would be a limited hero and uh, let's just say I think we've all noticed how meticulous SG's QA team is. I find in the day and age of Hwa and Rimuru, where you can be hyper-tanky and still oneshot things, it's sometimes a bit hard to be a dps and also stand out. Factor in that I especially wanted to stay true to the gimmick when building his kit, it was somewhat difficult. 

Anyways, I hope it isn't too bad. Enjoy~!

Zenitsu: Fire Thief 

Unique Debuff: Slumber - The caster is incapable of activating a dual attack or counter attack. This debuff cannot be cleansed or have its duration decreased, but it can be broken if the caster takes damage.

Thunder Breathing: First Form: Strikes the enemy with a sword, (with awakening: before activating I’M GONNA DIE). If this attack is used while Zenitsu is asleep or in a slumber, it increases Zenitsu’s combat readiness by 20% (with awakening: and instead of activating I’M GONNA DIE decreases the cooldown of You Must Master A Single Thing by one turn).

Cowardly Disposition: Zenitsu starts the battle in a slumber. Once per turn, when Zenitsu takes damage, he activates I’M GONNA DIE. Whenever Zenitsu is asleep or in a slumber, he gains 100% dodge chance, and has a 20% chance to counter attack with Thunder Breathing: First Form whenever an ally takes damage. 

     I’M GONNA DIE: Zenitsu screams in fear, dispelling 2 buffs from the last enemy who hit him and inflicting redirect provoke on all enemies, before falling into a slumber. 

You Must Master A Single Thing: (cooldown 9 turns with mola): Whenever Zenitsu or an ally would die, Zenitsu offsets the damage that would cause them to die (leaving them at 1 health) and activates Thunder Breathing: Sixfold on the enemy who attacked them. 

     Thunder Breathing: Sixfold: Zenitsu falls into a slumber before attacking the enemy with a swordstorm, penetrating their defense by 50% and healing based on the damage dealt. If this attack kills the enemy, increases Zenitsu’s combat readiness by 100%.
