Summary
It was all over anyway..
So when Mephisto told Rin that the only way for him to live is to transform into a blue-flamed cat-demon and be Yukio’s familiar, he accepted his fateOr
When Rin destroyed the gehenna gate with his newly awakened flames, Mephisto gave him a deal: if he transformed into a blue-flamed cat-demon and became Yukio’s familiar, he could live. Only Yukio and Mephisto would know the secret about him.
Rin’s appearance as a cat-demon:
Light blue sleek fur, white paw pads, light blue eyes, two small hors on forehead that swirl with blue flames, a flame-looking patch on forehead, big pointed ears, long twisted tail (kinda same as the demonic tail he has in the anime and manga) and large bat-like wings

Summary
Rin Okumura grew up, not knowing who he is or… what he is.
But everyone else knew. All the time they knew. They knew he is a demon.. a very powerful and possibly dangerious demon.Shiro fujimoto, a human who raised Rin and his twin brother Yukio, decided that if he needs to, he will make Rin his familiar demon to protect him if/when his powers awaken. This was because there is a law that says: 𝐲𝐨𝐮 𝐜𝐚𝐧 𝐧𝐨𝐭 𝐤𝐢𝐥𝐥 𝐚𝐧𝐲𝐨𝐧𝐞𝐬 𝐟𝐚𝐦𝐢𝐥𝐢𝐚𝐫 𝐝𝐞𝐦𝐨𝐧.
No one can change or come across that law, not even grigori.Yukio, who doesn’t have any demonic powers, knows about Fujimotos plans for Rin.
However, when the day his powers awaken came to be, father fujimoto died while being possessed by Satan, Rin and Yukio’s biological father. Rin managed to escape Satan and the gehenna gate that was about to swallow him by breaking the very sword that contained his demon heart. The power of it exploded the gehenna gate and transformed him into his true demon-form. Blue eyes, pale blue -almost white hair, white tail, fangs, claws, small horns, blue flames, all.
And thats when he knew, everything had changed, and nothing will ever go back to normal anymore.

Summary

Izuku doesn't want to open the box.
OR
Izuku didn’t return home after school. Two months later he was found roaming a deserted road with white hair, psychogenic amnesia and a quirk out of control.
Nothing is the same after that. -

Summary
“Mother had told him where to go, and who to look for. She told him he needed to stay hidden and not trust Man.”
“But he didn’t understand. She was sending him straight into a large Man clan. He could smell hundreds just from where he was now. He assumed that the one he was looking for was like them but each step closer he took the less he believed that was true.”
“He shook his head before continuing on his journey. This is what Mother wanted and he felt shame trickle down his back. How could he second-guess her? This is what she told him with her last breath.”
After his mother is killed, Izuku makes his way out of the deep forest and into Man territory. He needs to find the one his mother sent him to look for but Man are dangerous. And he’s about to be reminded of this first hand.
But what if they all aren’t bad? What if he quickly finds himself coming to trust a few?
