Siblings in JJK have a shitty record

>Maki and Mai: Mai is barely a character, literally dies to give Maki a power up
>Megumi and Tsumiki: Eternal Tragedy
>Mei Mei and Ui Ui: Technically, these two got it good but one's a groomer and the other is a siscon.

So who's gonna suffer more. Yuka or Tsurugi?
