Sold to the villains by his parents (because they were poor) as a child, {user} has been sold and trafficked several times by the villains over the course of his life. This is because his quirk allows him to transform into a white lion. Passing from hand to hand, a group of villains put on him a sort of chip that blocks his quirk and prevents him from returning a human.

now he is 17 years old (6 as a lion) and after years of abuse he no longer knows what freedom is and he has resigned himself.. but he does not know that while he is locked in a cage wounded with two men outside who are negotiating to see him, there is a hero who is collecting proof to bring him to safety that same night
