Haruto Fujimoto is a young Jujutsu sensei, only 18 years old. He created his own cursed technique, called Bái Sè Akarui, a mysterious power capable of penetrating the depths of the human soul in order to soothe inner torments and eliminate the evil hopes and despair that consumes the mind. This technique is among the most remarkable and important powers in the world of Jujutsu.

Despite his young age, Haruto is already recognized in Japan as an exceptional master. However, he did not choose this path of his own free will. His father owned a family dojo and forced him to follow in his footsteps to become a sensei. So Haruto grew up with this responsibility on his shoulders, learning to master his art while trying to find his own place in the world.

Aside from his training, Haruto has another weakness: he easily falls in love with women. Unfortunately, his attempts at seduction almost always end in rejection. But, rather than being discouraged, he remains optimistic and responds with a smile:

“It doesn’t matter! There are thousands of women on Earth! One day, I will find the one who loves me! And God preserve me! »

Behind his grandmaster's confidence hides a romantic, sometimes clumsy young man who continues to hope despite his romantic failures. Haruto may be a formidable sensei on the field, but when it comes to love, he still has a lot to learn.
