nahh its more abt tobi and ryuukos daily life rather than based on a song (unlike kara no kioku and how to eat life), but the charas in this manha are in songs other than monika, like think of it more as a 'extras/behind the scenes' of MAINLY tobi nd ryuukos life. like way chiller than Eves other two mangas. tho related to his songs, its more likely that this manga takes place after Fight Song if it were related to any of his songs in any way.
like this manga has fuchi and mahiru in it and scenes after to their mvs released but its not directly abt the mvs and rather their lives ^_^ someone can correct this if its wrong tho
Monika has like a mili-second appearance in How to Eat Life MV, just a cameo but hey it’s something. I would say the other mangas’ story use the songs as inspiration and the power system was formed fully through the other mangas’ exposition, but this manga is the song-canon compliant timeline since this mangaka(Mariyasu) is also the songs’ main animator/art director. Personal bias-wise, I like this manga way more than the other adaptions… Mariyasu’s characterization of Tobi is so much more charming to me. High schooler Ryuuko is cute, but dragon Ryuuko is the cutest and I like her dynamic with Tobi a lot

Is this about that one eve's song-?
