Overtime Notes from a Jujutsu High Dorm Supervisor

An "ageless" technique + an extreme fear of death ≈ a menace who lives for a thousand years.

Kamo Yuuji doesn't want to be a menace. He just wants to lie flat and drift through life, so a thousand years later, he holes up in Tokyo Jujutsu High and becomes a dorm supervisor who spends all year lounging on a sun chair.

"According to the surviving ancient texts of the Three Great Families, the Fujiwara family was one of the most prominent jujutsu sorcerer clans during the Heian period a thousand years ago..."

"The Fujiwara family?" Young Nanami Kento frowned. "If they were such a major clan, how did they suddenly disappear from history?"

"Apparently, they had a spendthrift heir," Kamo Yuuji sighed calmly. "Seems that wastrel lived quite a long time, but even a great fortune can't withstand being squandered..."

"A spendthrift heir?" Young Nanami Kento paused. "I didn't see anything about that in the books."

"Maybe he left the jujutsu world for another line of work, so it wasn't recorded," Kamo Yuuji sighed again. "He might've switched to being a dorm supervisor."

Nanami Kento: ... (cold stare.jpg)

During one battle, Kamo Yuuji was, as usual, hiding in a corner and slacking off.

"Isn't that Fujiwara?" Sukuna, who was indiscriminately attacking everyone, noticed him in the corner. He paused for once and let out a loud, mocking laugh. "You've really gone downhill."

Kamo Yuuji: (crouches in the corner) (draws a little circle and curses you) It's all because of you try-hards, secretly grinding away behind my back for a thousand years...

"Tsk, tsk," the King of Curses shook his head. "They've even stuck you on the sidelines in a fight. How embarrassing."

Kamo Yuuji: ... Sorry, I haven't fought for the spotlight in years.

"Tsk, tsk," the King of Curses continued, shaking his head. He teased, "At this level, you were trying to seduce me a thousand years ago..."

Kamo Yuuji: ? (interrupted) (loses it) (expands domain)

A few tips before reading:

1. There will be flashbacks to the past, including the Heian and Meiji periods.

2. The likely pairing is Nanami. There may also have been something with Sukuna in the past.

3. The protagonist has secret identities. This isn't a typical playing-the-pig-to-eat-the-tiger story.

4. It may look silly, but the tone is actually more serious.
