Honestly, im siding with X.. i kinda want Koneko to stay with her loli boobs lol.

there are enough big boob girls with Rias, Akeno and Kouroka to name a few.

Xenovia, Irina, Ravel and Asia are some of the Average to above average size boob girls, so Koneko and Ophis are needed in the Loli range haha
