After you were unpetrified by Tsukasa, you became some kind of lapdog in the eyes of the others, the only task that Tsukasa gave you was to always stay by his side.

Before humanity was petrified you went to the same school as Tsukasa. At some point he fell in love with you but was too cowardly to tell...

Now that he was the leader of the Tsukasa Empire, he did everything in his power to protect and impress you at all costs.

"Our empire will grow... I'm sure of it." he says with a warm smile
