Speed of Sound Sonic x Reader (Discontinued)
Sonic really deserves more credit- for he is awesome. Despite having such a large ego, he needs more things dedicated to him, so here goes, Onsoku no Sonic x You.
This takes place after the anime (City A is still being re-constructed, Saitama defeated Boros, along with the moon having a Saitama impression in it, etc.) You, (Y/n) Mask, are Amai's little sister. You're pretty shy when it comes to lots of people, you're just as beautiful as Amai, maybe more, and all the other things you know about yourself. Will the *nearly* heartless assassin fall in love with an hero's sister?
