Ore-sama

Ore-sama (Japanese: オレさま) is a common expression by Moe. In Japanese, it is seen as a very arrogant way to refer to oneself; however, it occasionally appears in Japanese media/otaku culture as well (a 'rude' way of speaking is similar to how characters such as Luffy from One Piece speak, but Japanese people do not expect this in real life).

In the fan translations it appears as "the great Moe".
