	+ Due to Kon's great deeds he seems to have replaced Agon with Kon as his rival striving to surpass him instead. **Ch 193**

## Affinity

## Abilities

* Sei didn't know yet but the mirrors were his special ability as a human. The world inside it was his inborn power as a demon. Coincidentally both powers meshed well together, and if he mastered them both, Sei would become the strongest exorcist ever to exist. **Ch 96**
* His ability is too versatile and strong to boot. He could fly by levitating the mirrors, store things and people, reflect attacks, and in the future, he will discover a lot more about it. **Ch 103**
* Inside the mirror, time doesn't move slower or faster. But from what he had seen so far, it moves at random intervals, or at least he hadn't been able to find a pattern yet. **Ch 146**
* His hair has started to flash silver and his eyes glow when he uses a certain level of power. **Ch 162**
	+ Anika thought she glimpsed a phantom fluffy tail behind him when his hair flashed silver. **Ch 170**
	+ If his hair unintentionally turns white, it would indicate the presence of the nine-tailed fox. Sei served as an unwitting Tamae No Mae detector. **Ch 190**
* Sei's mirror was truly remarkable, possessing an undiscovered function that would only become known much later. It served as an artefact connecting to the outside world, a creation only someone with Sei's extraordinary talent could achieve. **Ch 192**
* Inside that mirror lies the culmination of humanity's hatred towards demons—an impeccable anti-demon weapon. Sei's unique abilities and hatred towards demons had given rise to something deadly... especially for your kind. It was an unwise decision to possess his mother's body, the source of his resentment. He tailored his special ability to kill her. **Ch 192**
	+ The reason why the demon world inside the mirror weakened demons to such an extent was due to this entity. **Ch 192**
	+ an existence defying logic, akin to a black hole hovering inches from Kon's face, obliterating everything around him while leaving him untouched. It tugged at his thoughts and his sanity, shattering his mind into fragments before reassembling it, making him whole once more. Once again... Whole..? **Ch 193**
	+ a bizarre creature, an amalgamation of geometrical shapes. Its head was a leg, its mouth a nose, and its finger resembled an eye. Skin spikes adorned its form, and it seemed to emit an eerie spinning motion. **Ch 193**

### Absorption Mirror

* The Absorption Mirror was a broken ability. But it could manifest only within a radius of around two meters from Sei. **Ch 26**

### Ultimate Technique: Mirror World

* mentioned in **Ch 94** as a future powerup
* It weakens foreign creatures up to and including Agon at Stage 2 **Ch 96**
* This barrier transported them into a world of light and mirrors. Every wall, flower, grass, tree—everything—was made of mirrors. The only things that stood out were the things that had entered this realm. This was the pinnacle a Creator could achieve—creating a barrier around the world in their mind and technique, and manifesting it. **Ch 217**
