[Dual progression and romance plotlines] + [Old-version Giyu and Shinobu] + [Tanjiro and Kanao]

This is a world where spiritual power awakens and demon beasts run rampant.

Everyone can awaken a martial arts talent and establish bases to fight against the demon beasts.

Yet the true terror is not the demon beasts, but the immortal beings who fear only sunlight: demons.

Kamado Tanjiro sets out on a journey to find a way to turn his demonized younger sister, Nezuko, back into a human.

Introduced by the strongest warrior, Giyu Tomioka, he enters Demon Slayer Academy, where he meets the gifted warrior Kanao Tsuyuri and a group of companions who fight by his side.

His "Boundless Sight" can see the essence of everything. He can discern the nature of any material and read people's hearts through their eyes.

As a result, he also discovers a few little secrets about some people at the academy.

For example, Mr. Tomioka claims to be married, but Tanjiro has never seen him bring his wife around. What's more, he's always very close to Ms. Shinobu Kocho.

Then there's Ms. Shinobu. She doesn't talk much, but she seems to love spending time with Giyu.

Their relationship...

Seems a little unusual...
