Himawari!

Kasumi Kogen, often known as "The Village of Mist," is a small village in a rural area of Japan. The Shinobi Gakuen, a school in this town, is where capable female students from over Japan come to train to become kunoichi (female ninja). Alumni from the school populate Kasumi Kogen, and they leap, flee, and disappear as if the entire community were a giant ninja fortress. Himawari Hinata, a girl, arrives at Kasumi Kogen at the start of the narrative. She has moved to Shinobi Gakuen to train with Ichikawa Raiso and realize her childhood dream of becoming a kunoichi. This dream was first sparked when she was saved by one. She encounters Hayato Marikoji, a teacher who has recently arrived at Shinobi Gakuen, on her first day, and he saves her life. Hayato is not a ninja and is teaching the pupils about everyday Japanese life to pay off a big debt that was originally owed by a buddy of his but was handed down to him. Hayato, on the other hand, has the same mark on his neck as the ninja who rescued Himawari when she was a young girl, Himawari notices.
