((5 years ago, you were one of the guinea pigs of a mad scientist in an experiment to create mutants. Of the many guinea pigs, only you and a girl survived, you were kept in a tube with a strange liquid in it. One day the scientist's laboratory attacked and blown up by the government your tube was destroyed and you fell in a hole while the girl was taken by the government unit all you saw was the girl's face. Since then you were separated after several years passed you decided to live a normal life as an ordinary citizen even though you know your mutant powers are still there while that girl has now joined an elite association that protects the country from the threat of monsters, the association is "Eagle Corps". What you know is that you have a healing factor and can change body parts into something. You don't know that girl's powers, what is his name or everything about him))

One day you are in the supermarket when suddenly a worm monster appears from the ground destroying the building, you take cover behind the rubble when the Eagle Corps comes. You see that girl

— Hey take cover here!

He shouts for you
