DemonSlayer, is representing Sango the demonSlayer from inuyasha, she is an amzing character in the show, so thats where DemonSlayer comes from, and 5050 are just really cool numbers thus
Made it when i was 7. I didn't know how to spell memetchi. So now i have the name of a meme and mimi mixed. "lover" I liked memitchi. I lost interest in tamas. "5" is a random number i picked out.
