The father of Mai and Sanae Toyama. He pushed his way into marriage with his wife, a painter, by saying they shared art in common.

Unlike his wife, who specializes in abstract art, he focuses exclusively on 2D anime-style girls. After the company he worked for went bankrupt, he lost motivation and became a hopeless slob, ending up estranged from his entire family.

That said, he did help get Mai a job at Iris Corporation, so it seems he's not completely cut off. Still, Mai wants nothing to do with him and seems to actively avoid him. There are even rumors that she once tried to kill him...?

He's as rough as he looks, but he's nice to people who flatter him. Thankfully, both Iris Corporation and Sayaka figured out how to deal with him easily enough...
