However, she's not the only one looking for them. "I'll wipe out Hameruda!" Rin's friend, Kyoko Kishibe, is furious at Hameruda for what they did to her friend. Kyoko, disregarding the danger, attempts to get captured by Hameruda herself to infiltrate their base. To protect Kyoko and rescue Sumire, Rin follows Hameruda to a ruined shopping center. Is Sumire really there? Can she save Kyoko? To save her friend who has been taken hostage, Ristia offers herself and accepts Hameruda's ejaculation. "I, I can't feel anything! If I cum now, I won't be able to go back!"
