One my favorite scenes in Majikoi S
Mysterious Voice: Take my shaft...do not fear.
Yamato: W-Where's that voice coming from?
Mysterious Voice:I am the great divine blade "Sword of Kusanagi." I am the one that dwells in thy crotch.
Yamato: My dick is talking to me?
Mysterious Voice: You have received a gift from your father.
Yamato: What are you saying all of a sudden?
Sword of Kusanagi: Retreating due to the fact that she is a small girl is unacceptable of a man of the house of Naoe.
Yamato: It's fine if I'm not a man of the house of Naoe, I want to be a gentleman before that.
Sword of Kusanagi: Don't act innocent, and act as you wish.
Yamato: Are you telling me to sell my soul to the devil?
Sword of Kusanagi: Henceforth, the devil will smile!
