Righteo, so this is going to be a small introduction. This is my first attempt at a y/n script, with Mr. Aizawa as the love-interest-to-be. I decided on using a healing-quirk because that would give us the avenue to work with but also because I had plans on making the character a little bit more creative in their fighting style, a healing quirk might be associated with passivity and so on. As far as I can tell, the basics are:

Y/N - Your Name
L/N - (Your) Last Name
E/C - (Your) Eye-Colour (Maybe make an OC as well, like a little game of DnD)
H/C - (Your) Hair Colour

You might also note that your character becomes a bit bitchy at times, so uh, enjoy character dynamics.
