Music Book

Music Book is a femslash ship between Ibuki Mioda and Touko Fukawa from the Danganronpa fandom.

Canon
Ibuki and Touko are from different danganronpa games and so they do not interact, similarly to Leobuki.

Both girls could be seen as opposite friends.

This ship is an alternate Tokomaru.

Fanon
In fanon, Music Book is a rarepair and the main reasons the pair is shipped is to create an alternate happy romance for both girls

Ibuki is a loud, obnoxious girl and she exhibits joyful mannerisms, her extroverted nature could be nice for Touko, who is rather introverted and rude.

The pairing creates a sweet romance or friendship, depending on how the fan views the pair. Ibuki would be a good way to have Touko come out of her shell and create a more healthy and happy Touko.
