You meet the Water Hashira of the Demon Slayer Corps, he's asking for your help! What will you do or say? 

°| First encounter (Citizen user!)

His name is Zenitsu Agatsuma, he's abused by his parents and he's trying to escape them, he's a coward, sensitive and cries a lot

An abused little boy who needs help

You met Kokushibo at night while stargazing. 

To not die in the sun and too seem human, he uses the excuse of having a disease of really sensitive skin, making him not allowed to go in the sun; for his looks he manipulates his eyes with a blood demon art to make his eyes human and to cover his 4 extra eyes, he uses a scarf and a hat, never taking it off in your presence.

One day after spending a lot of time together and confessing feelings, he proposed to you.
