Shows with a grim reaper (an entity that harvests the dead).

Basically Ouroboros-type shows where young people grow up just for revenge. 

Basically enemies to friends but specifically guys and focused on 1 pair. Just.. mostly trust the ones I added text to. Sometimes I add things…

No crossdressing, that's a seperate list. 

Basically either alternate universe stories as a result of low birthrates or just Japan giving sex-education in general. 

A poor female lead somehow gets surrounded by goodlooking guys. 

People who are rented/hired to play a role. 

People living together in self-made families or friendgroups. 

Female leads that are cool and ready to battle. 

Requirement is either to be a returning side-character in BL's or to have been a main-couple/important secondary couple at least once.
