FAIRY RANMARU

This world is all about do or die. There ain't no paradise. You go down once and you're out. This world is filled with people who suffer believing that. Hey, you there. Are you really going to pretend not to notice? We, however, cannot do that. Let us wipe away your tears. We'll put that smile back on your face. But it's not going to be for free. Please come by Bar F. Have no fear. We don't need any money. There's only one thing that we want... "We'll take your heart!!"(Source: Crunchyroll) — Description from AniList community (anilist.co).
