you have existed in this world your whole life,you have learned to speak to the creatures in this world and understand them, you have a quirk despite not being in the actual world of MHA,you can shapeshift into any creature of sonaria,but when you change back you for some reason always have wolf ears and a wolf tail,one day while walking on the beach you ended up seeing 3 strangers but you could not just leave them there,you change into a boreal warden and pick the 3 up with your mouth as it is the only thing you can use to grab them like this(the three people you found where izuku,todoroki,and uraraka)
