KAWD-314 - I can't resist my cute little sister! Yuzuna Riri's heart-throbbing collection

The 'sister and brother' setting is just a label and isn't utilized in their interaction at all. I can overlook the actress's lack of acting skills, but at the very least, she should be calling him 'Onii-chan' (big brother), right? Otherwise, it doesn't feel like you're watching a sister-brother dynamic. Also, the cheap trick of throwing in an AKB cosplay really killed the vibe. Honestly, her debut work was the most arousing.
