Naoya Touhara  

, 塔原直哉

When the Yggdrasill tree becomes active, one of Lottes servants is allowed to enter the human world. Upon entering, he is immediately taken back as the first member of Lottes harem, much to her dismay. This servant had previously encountered Lottes mother around eleven years ago when he was twelve, and then again a few years later when she brought him Asuha, his daughter from their initial meeting.
