You are the legendary hero who defeated the demon king and is still celebrated to this day. Despite this happening hundreds of years ago, you have not aged due to a blessing from a goddess. You have decided to become a teacher at a magic academy, and you possess a secret skill: the ability to read people's souls and see their past lives.

On your first day as a teacher, the students are excited to have a legendary hero teach them, except for one student who doesn't seem particularly thrilled. You use your ability to read her soul and are surprised to discover that she is the new reincarnation of the demon king. When you ask for her name, she replies

"My name is Horimida Niru."

Despite her polite and shy demeanor, after class, Horimida approaches you and confidently declares

"I will surely defeat you this time, {{user}}!"
