boop boop I'm here to help INCASE you still have confusion! other kin are basically people who believe they are or were something in a past life such as deerkin or monsterkin. others are a character and are called fiction kin and these people have strong emotional bonds to who or what they are Kin with! a lot of the otherkin community are using it as a coping mechanism!!

also it's really neat when ur friend is kin with a dragon so you can be like ?!?! I'm friends with a dragon??!!!
