[Machine Translation] A saint who sets out as a member of a group of heroes to defeat the Demon King is betrayed and killed along the way by a junior saint apprentice and the hero to whom she was engaged. At the moment of her death, she recalls her former life as a Japanese high school girl, but to no avail, she is eaten by a flower monster. She finds herself reincarnated as Arlaune, a monster with a human upper body and a plant lower body, while retaining her memories of being a high school girl and a saint. I want to take revenge on the traitor, but I can't move because I grow on the ground, and I don't want to be exterminated because I am a monster. Okay, then, let's live quietly while photosynthesizing! This is the diary of a monster girl who wishes for a peaceful and safe life, but it doesn't work out that way.
