what is kirisaba???

The following photos source lparchive and the danganronpa wiki

kirisaba is the ship between kyoko kirgiri and mukuro ikusaba. hopefully you already know what danganronpa is, but even then, you're probably not familiar with the interactions between them. let me give you a summary about their interactions to be concise:

mukuro ikusaba helps her sister junko enoshima trap their classmates into a ace attorney style battle royale death game, wiping the memories of their peers. she immediately gets killed by her sister. kirigiri is the first one to discover ikusaba's identity as the "ultimate despair", resulting in a rather over-used meme.

the 16th student. lying somewhere in this school.

kirigiri does an autopsy on her. Naegi, the protag, says he feels sad about leaving her body lying in the morgue. Kirigiri does NOT feel bad for ikusaba.

Kirigiri: Sad...? Did you forget? She was our enemy once. A part of the Ultimate Despair.Naegi: B-But she still got killed. She's still a victim...Kirigiri: Have you ever heard the phrase you reap what you sow? Naegi: W-Well, yeah, but still... Kirigiri: ... Kirigiri: you really are naive, you know that? It's really quite appalling... Naegi: But she could have abandoned me...but she decided to help me instead. So for someone like that, what does it mean to be naive?

Well, that's all folks. Thanks for reading. hopefully i've convinced you of why kirisaba is peak.

Okay that's not all. danganronpa is a franchise, meaning they have non-canon interactions too.
Ultra Talent Development Plan is an alternate universe set before the death games. ikusaba and kirigiri are friends! only ikusaba isn't really herself. she's pretending to be her sister. oh did i forget to mention that ikusaba switches identities with her sister.

Himiko: Hm...if you say magic is real, then Junko will have to believe it. Mukuro: Ah, now you've done it. Don't you know? Kyoko can definitely figure out all the gimmicks to your magic tricks. Himiko: No...there's no gimmicks or tricks in my magic! Kyoko will tell you! Mukuro: You heard her, Kyoko. Make Himiko realize that all her magic tricks are just gimmicks. Himiko: Alright...watch and be amazed by magic, you two. Kyoko: I never actually said I would watch the show yet...oh, she's gone.

note Ikusaba's interest in kirigiri's detective work this will be relevant later on.

Today is the the sports festival... [Kyoko is] in the three-legged race! It's not your style, but you don't want to drag anyone down. Who should you be careful of? Kyoko: I should discuss this with my partner. Let's do  our best, Junko. Mukuro: You don't look athletic, but your P.E. grades are pretty good, right? I'm relying on you then! Kyoko: That's my line. I can tell from your movements that you exercise quite a bit. Mukuro: Well, models do need some physical strength. And I need to keep my figure, so I exercise a bit. Mukuro: Did ya get a good enough look yet? You're very observant, Ultimate Detective.

cute right? aknowledging each other's talents...interesting. i'm going to link a video for this next udtp interaction because i think it's more sentimental with the ost.

cute right? ikusaba is empathetic towards kirigiri's hard work and considers her schedule for the christmas party. kirigiri treats ikusaba as if she's enoshima, but she's not particular about exposing other's identities if it's not related to a case.
