I quite like how open-ended some of the dialogue is vis-a-vis the theme of immortality. Mokou just sort of awkwardly going along with the conversation with Yuyuko or Reisen saying "Well, Eirin knows best, she's been around a long time..." Gives us a glimpse at how she feels, but leaves it up to the audience to ponder on it deeper. Also, the writing between Mokou and Keine is cute!!
Thank you for the game!
