Im_Your_Daddy
Yato is in trouble, and Yukine is nowhere in sight. So, he gives a name to a new weapon. But she doesn't speak. From the very beginning, she gave no trouble, and Yukine gets jealous quickly.
The name the mute girl was given, was Hatsune.
Regalia name: Yukki .:. Haruna
(( Hatsune means 'first sound', and since it's about a girl who doesn't speak... Heehee. ))
