Wataru's got feelings for Isumi, but he's stuck in an arranged marriage with Nagi—which obviously complicates things. Unlike the wealthier cast members, he's not rolling in money. Instead, he runs a video rental store with his maid Saki Kijima, and they're often scraping by. Late returns are a constant headache, especially when Nagi's the culprit.
By season 3, he's switched gears and opened a manga bookstore instead. Saki's still working alongside him, though she's traded her usual outfit for a pinkish maid uniform.
