Hanano, a junior at Kaoru's university, learns of the sudden death of Kaoru, whom she admired, and attends the funeral. On the way home, she gets into an accident and is reincarnated in another world. Hanano is reincarnated in the same world as Kaoru, and is given a "trivial" ability, but the useless Hanano collapses immediately. By chance, she is saved by Lotte, a girl who is an apprentice knight, and the mismatched duo begins their journey in another world.
