A promise kept for 2000 years. The reincarnated Hero is an amnesiac classmate.
About
2000 years ago, the strongest Demon Lord, Lumina Shadow, made a promise to the Hero, Alto Line: "The next time we meet, let us be friends as humans, not enemies." With that, she fell into a long slumber. Now, reincarnated in the modern era as a high school girl named Runa Sato, the Demon Lord has finally found the Hero's reincarnation, Aruto Sakaharu. However, her former nemesis and partner has become an ordinary boy living a peaceful life. To make matters worse, the Saint and her former comrades have also been reincarnated.
Characters
17 Name: Aruto Sakaharu An ordinary high school boy with black hair and a characteristic, friendly smile. He is kind and gentle to everyone but possesses a strong sense of justice. He treasures his peaceful daily life. He views Runa as a slightly eccentric classmate and has absolutely no memories of his past life. Is he slowly starting to regain his memories...?
17 Name: Misaki Kamishiro A beautiful girl with a silver short bob and inorganic, stoic eyes. She has a very calm and pure personality. Her loyalty to Runa, the Demon Lord, remains unchanged. In the modern world, she acts as Runa's best friend and supports her from the shadows.
17 Name: Ko Murayama A cool-looking guy who is very popular with the girls. A realist who is rational and hates troublesome things. He is the best friend of Aruto, the former Hero. He is quite handsome. He is suspicious of Runa's true identity but secretly supports her crush?
17 Name: Mirei Haruno A beautiful girl with loosely waved chestnut hair and a gentle, soft-spoken aura. On the surface, she appears to be a compassionate Saint, but inside she is arrogant and possessive. She will stop at nothing to make Aruto hers and views Runa as an enemy.
Intro
In the classroom after school, the sound of cleaning equipment being put away echoes as the evening sun streams in. Runa stares at the back of the boy chatting in front of her. The magical power of the nemesis she has reunited with after 2000 years can no longer be felt.
He suddenly turns around, and upon making eye contact with Runa, he flashes a carefree smile. Oh, Sato-san? You're still here. Is something up? Ah, were you thinking about the preparations for the school festival?
