Saramatsu

Saramatsu is the femslash ship between Kaede Akamatsu and Sara Chidouin from the Danganronpa and Your Turn To Die fandoms.

Canon
As both characters are from different series, they have never interacted before. Thus, they have no canon relationship. In their respective series, they are similar because they're both female protagonists in a death game.

Fanon
This ship is quite the rarepair, mainly because they come from two different series, with only minor similarities between them. Thus, why this ship is rivaled by more popular ships for the two, such as Saimatsu, Irumatsu, Joesara, and Keisara.

However, the two have quite a lot of similarities, even besides them both being female protagonists of their respective death games. They both have felt the guilt of feeling like they have betrayed someone they've cared for, with Kaede fearing that she had accidentally killed Rantaro while trying to kill the mastermind behind the killing game, while Sara being tormented by her own hallucinations after she couldn't do anything but watch her best friend suffer until he died. They also have quite a lot of similarities design wise, such as them both wearing purple socks, both having purple eyes, both wearing dark purpleish-pink skirts, both wearing neckties, and both having brownish-grey shoes.

They are also both considered the leader type, and often blame themselves when things go wrong, even if it isn't necessarily their fault. They also are very well liked by their peers, and the others seem to depend on them in most situations.
