How Can a Dark Mage Not Be in a Hot-Blooded Manga?

* (I'll start this after I finish Prince of Tennis...)

In his previous life, Mochizuki Seiichi was a genius mage. After traveling across the continent, he chose to take his own life. The last good deed he did was leave his corpse in the Demon King's lair.

Ready to explode at any moment.

When he opened his eyes again, Mochizuki Seiichi discovered that he had begun a new life with his memories from his previous one intact.

At the age of two, Mochizuki Seiichi began testing how well his new body could handle magic. To his delight, he discovered that his talent was even more outstanding than in his previous life. He was practically born for magic.

When he was five, Mochizuki Seiichi cast his first complete, complex spell, turning his cat pure white and giving it blue eyes.

After transforming, the cat was especially bad-tempered. Mochizuki Seiichi was a bit of a pest, and the more aloof the cat acted, the more he liked clinging to it.

When he was ten, he went out to play with his neighbor Gon and encountered an evil magical creature. Mochizuki Seiichi fired a magical shockwave and blasted the creature to ash.

Gon asked cautiously, "Is Seiichi a psychic too?"

Mochizuki Seiichi answered seriously, "No, I'm an ultra-super-cool great mage!" Although he was only at the level of a beginner mage for now, he would become a great mage soon!

That night, while Mochizuki Seiichi was fast asleep, he felt someone pinching his cheek. When he opened his eyes, he met a pair of beautiful blue eyes exactly like his cat's.

Wait?!

Was it finally his turn for that story where you raise a cat until, one day, it turns into a person and spends the rest of its life with you?

Mochizuki Seiichi, a full-on cat addict, got excited and sat bolt upright. "Kitty, I knew it was you..."

Wait, his cat was a boy.

Mochizuki Seiichi faltered. He looked at the white-haired boy sitting on him with a sour expression, shut his eyes, and lay back down. "It must be a dream, hahaha..."

It turned out his cat had a name. From that day on, every night, his cat would turn into a person and torment him.

He wanted to learn magic and barriers, and kept asking where Mochizuki Seiichi had learned all this stuff. He was a walking encyclopedia of questions.

Mochizuki Seiichi sighed. Well, well, he might as well humor his own cat.

At fourteen, his neighbor Gon decided to give up on high school and attend some religious school he'd never heard of. Holding his own drowsy cat, Mochizuki Seiichi quietly asked Gon, "Is your school for people with psychic powers like you?"

Gon corrected him. "No, it's for jujutsu sorcerers."

"Are there any mages like me there?"

Gon, also known as Suguru Geto, hesitated, then shook his head. "I don't know either."

The drowsy cat suddenly opened its eyes, looked up at Mochizuki Seiichi, and bit down on his slender, pale wrist.

"Hey, what are you doing?!"

-

One day, Mochizuki Seiichi ran into his neighbor Gon on the street and sadly told him that his cat had gone missing.

Gon comforted him. "Why not get another one?"

"All right, I guess I'll go to the pet shop and pick out a similar one to raise." Mochizuki Seiichi sighed glumly.

That night, while Mochizuki Seiichi was fast asleep, he was woken up by another pinch. Meeting those beautiful blue eyes, he asked, bewildered, "You already turned into a person on the day I brought you home? You look so much like him."

1. Light Megumi Fushiguro, mainly Jujutsu Kaisen, with side stories and a main plot

2. Seiichi's growing-up diary + cat-raising diary

3. Adoptive family

4. His biggest golden finger is probably himself. His way of leveling up is to transmigrate through time and space to save his cat (the mid-story main plot).

5. Extremely overpowered, wildly beyond the limits. Unrivaled high-magic combat power, with magic shockwaves going head-to-head against one another.

6. (Important) Main plot about the Gojo family, no teacher storyline!! Read with caution if that's not your thing.
