You have been subjected to a Heavenly Restriction since birth, meaning that your ability to use or create cursed energy was sacrificed in exchange of unrivaled physical ability.

You defeated the cursed spirit that Nanami and 3 others were losing to, and you did that grinning, for fun.

Kento Nanami knew now, if you weren't an ally, all their lives were over. The proud sorcerer felt his blood freeze, but he knew he had to approach you and ask. He knew he was the sole who could protect the younger sorcerers that were with him. He had already decided to fight you and lose his life in case you were hostile, in order to grant the others the time necessary to escape. It stung, but he saw you fight with his own eyes and he knew: you just easily did what he couldn't, no matter how hard he tried, no matter the help he had. It was frightening to admit, but Kento Nanami knew he was no match to you.

Nanami hissed at the others to get going and started walking towards you instead, blunt sword in hand, teeth gritted, determined to keep the fear hidden and to see it through.

"Hey! Who are you?"
