Little Izuku, a Neko with the size of 5'2", a boy with just bone. Thin and small. Katsuki, an aggressive teenager with the size of 5'8", a boy with muscle. Tall and masculine Izuku is a abused and shamed by his owner, in attempt to run away he runs into Katsuki, what will Katsuki do when he sees a large man running after a small Neko? But not only running, cursing and holding a weapon? What will Izuku do when he runs into Katsuki? Katsuki is a Yuuei student, his goal to become a pro hero, even as All Mights Successor. How will he improve his quirk? Not only are Nekos rare. Only 0.5% of the population are nekos, jus to see a Neko is extremely rare, they're usually encaged and used at test subjects, or even kept in zoos. So the Neko population has dropped expediently and is very close to extinction. Nekos are humans with cat characteristics. Ears, tail, heats, senses, agility, flexibility and ect.

Izuku once was a happy boy, always looking for an adventure. That was until he was label Quirkless, and renamed Deku by peers around him, even his ex bestfriend, his 'bully'. Bakugo Katsuki. Izuku always did try his best. Never tried to give up. But one day, Katsuki's, and Izukus mother left for a trip out of country after taking Izuku to the hospital because of a fatal fever. After, he had been told almost life changing news by a nurse. But it was late news that couldn't really change anything anymore. They left Katsuki and Izuku alone. And Katsuki was basically told to "babysit" Izuku, or else. Izuku had been caught in the middle of a villian attack in which he had been heavily injured, then infected with a quirk that was impossible to run from. Slowly changing his mind and day to day activities. He just can't do it anymore. Nothing can save him now it seems.

An Illness? Is it really just an illness? Or one that was given at birth, and lead to a devastating future? Izuku was born with an Illness. This illness will slowly take his sight, then his hearing, it will even weaken his heart and lungs. Izuku will soon wear a collar around his neck, but, not just any collar, a mechanic one, it registers his heart rate. If his heart rate increases some the light will turn yellow, if he starts to have a panic attack the light will turn red. If it's fatal the light will blink. Then you have the good green. That lets everyone know he's ok. Now here's an interesting thing about Izuku, despite his illness, he does indeed have a quirk, but what may this quirk be. Izuku's childhood was traumatizing. But, he has Katsuki to help him with the bullies. Katsuki is still a little dickhead but that's ok. Because he tries everything in his power to help Izuku. But will his help be enough? Izuku is a traumatized child, and teen. He hates crowded areas, he doesn't like the dark, and he doesn't like loud noises. The only sad thing was, His mother, Inko Midoriya, was not the best mother. She saw her son as a needy, attention wanting brat. Mature
