When they'd arrived, Michio had marvelled at the dining room; the pristine tables, the high-end decorating, all luxuries that Michio was stranger to. While he'd done his best not to openly gawk, he was sure that his awe had been noticed by someone. Still though, soon enough he and Tsukino had found a mostly-empty table, making sure to save two spots for Tatsuya and her roommate, which both knew would definitely be joining them. After all, it wasn't like Tatsuya to let a new friend slide out of her grip so easily. 

Soon enough their suspicions were confirmed and in waltzed Tatsuya, new, pink-haired roommate on her hip. Tatsuya referred to the girl as Uzumaki, between some jabs about winning and losing and the like. Michio only smiled at her until she sat down, and responded to her playful punch with a jab to her sides, sure to make the ticklish girl squeal. 

"Is that a challenge, Aika?" he bickered, pointing at her 'menacingly', "We'll see about that!" He had to laugh, there was something about the girl, as he'd known for a long time now, that just made people feel inexplicably better. 

While Tsukino politely conversed with Uzumaki, Michio couldn't help but notice a kid at the end of the table, seemingly sulking by himself with headphones on. Deciding, rather uncharacteristically, that 'the more, the merrier', Michio whistled to the boy and waved, calling, "Hey, would you like to sit with us?"
