Tsubomi's emotions can be summed up in three states: joy, sadness, and pleasure. However, a previously unseen fourth emotion—anger—gradually breaks through her limits. In intensely stressful situations, the wrinkles forming on her brow, the hidden insults beneath her words, and her flushed, pouting face surprisingly come across as incredibly cute, making you whisper, "She's so adorable!" Her bell-like, pure voice rings out with an "Ah... angry voice," steadily heightening arousal. The domestic debut of the "angel's contempt"—a slight irritation shown in erotic moments—unlocks a brand-new charm of Tsubomi.
