The character I would choose to write sn essay on would be Zenitsu Agatsuma ftom Demon Slayer Kimetsu no yaiba. There is more to this lovesick anxious and cowardly lad. He knows about his flaws and wants to improve.
I'm a fan of Demon Slayer as well.
My latest purchase was a Nezuko Funko Pop moment figure when she was trapped in Rui's webs snd used her Blood demon art to help Tanjiro.
