- Casting Gag: Not the first time that Emiri Katou voices a cat-like creature who guides the protagonists.
- Playing Against Type: Chiharu Sawashiro is known for his performance as Banri Settsu from A3, the school delinquent who regularly fights with other students, games for days and always gets straight A's. Here, he plays Ethan, a very disciplined man.
- Kento Hama is similarly known for voicing Taichi from the same series, who has a very dog-like personality and wants to be popular with the ladies. In this game, he voices Sian, a Tsundere prickly guy. It's to the extent that it's barely recognizable, whereas you can still hear Banri in Ethan and vice versa.
- Relationship Voice Actor: Shun'ichi Toki, Kento Hama, Junta Terashima and Chiharu Sawashiro are actors in another universe.
