Yes, it is true. Like Miya and Maya Miyuki too has the genes for great stonking tits and deadly curves. In addition the Shiba are an ancestral branch family to the Yotsuba. Shiba Kuuya and Shinonome Maaya were the parents of the first Yotsuba head.
Both these two families were interbred with European parents who specialized in MI type magic. Tatsuya is 182 cm tall, for the record.

But Mayumi is the sexiest.
