This OVA was highly enjoyable. It made me realize just how much I miss this anime. Taeko finally got some screetime! I had no idea she was Ayumu's childhood friend (or maybe I forgot). It must feel bad to see him surrounded by all those supernatural beauties.
The card game was the funniest part of the episode. Orito was looking at Saras' panties while Saras was looking at Ayumu's ass, who in turn was looking at Taeko's breasts
No wonder Taeko and Yuki won.
