Nathan hesitated for a moment, clearly caught off guard by Mako's persistence. He shifted uncomfortably in his bed before finally sighing, realizing that his secret would get revealed to all of them anyway so there wasn't any point in keeping it hidden from them.
"Fine," Nathan said, his voice a mixture of resignation and annoyance. "But you better keep this between us. I don't want the whole world to know about it."
Mako nodded enthusiastically, his curiosity piqued. "Of course, I promise."
Nathan took a deep breath, preparing himself to reveal something he had never openly discussed with anyone. "The 'lava' skill you saw is actually my quirk. It's called 'Versatility.' I can exchange any one of my current abilities for a brand new one of the same level and skill level that I have knowledge about. That 'lava' effect is the result of me trading my Blood Wolf Transformation ability for the Explosion ability."
