Possessing the "ageless" magic + extreme fear of death ≈ causing harm for thousands of years.
Yutoki Kamo didn't want to be a nuisance, he just wanted to lie down and be a salted fish, so after a thousand years, he hid in a magic high school and became a high school director who lay on the sun lounger all year round.

"The Fujiwara family, according to the existing ancient records of the Gosan family, was one of the most prosperous families of magicians in the Heian period a thousand years ago..."
"Fujiwara family?" Young Nanami Kento frowned upon hearing this, "Since it is such a big family, how could it suddenly disappear from history?"
"It is said that a prodigal son was born," Kamo Yutoki sighed, "It seems that this prodigal son has lived for a long time, and no matter how big the family fortune is, he can't withstand the creation..."
"Prodigal son?" The young Nanami Kento was slightly startled, "I haven't seen that in the book."
"I guess I changed my profession from a spellcaster a long time ago, so that's why it's not recorded in the book," Yuushi Kamo sighed again, "Maybe he changed his profession to become a housekeeper."
Nanami Kento:... (Cold face jpg.)

A certain battle. Kamo Yutoki spends his days fishing in troubled waters in a corner.
"Isn't this Fujiwara?" Su Nuo, who was attacking everyone indiscriminately, noticed the corner, paused for a rare moment and laughed loudly, "It's getting worse and worse."
Kamo Yutoki: (crouching in the corner) (drawing a circle and cursing you) It's not like you scroll kings, you have been secretly scrolling behind my back for a thousand years...
"Tsk, tsk," a certain Cursed King shook his head, "Fighting has been assigned to the side, it's really embarrassing."
Kamo Yutoki: ... I'm sorry, I haven't grabbed the C position for many years.
"Tsk, tsk," a certain cursed king continued to shake his head and said jokingly, "At this level, you actually wanted to seduce me a thousand years ago -"
Kamo Yutoki:? (Interruption) (Breaking defense) (Field expansion)
Tips before reading:
①There will be interspersed episodes from the past (both in the Heian and Meiji eras)
②CP has a high probability of Nanami. There should also be some love lines between Su Nuo and the past.
③The protagonist has a waistcoat, which is atypical of literature that pretends to be a pig and eats the tiger.
④It seems to be unseemly, but it is actually a serious drama.
Intention: sink the boat against the current; if you don't advance, you will retreat.
