Chapter Summaries

Sogo Doma took Utaha Kasumigaoka to his underground laboratory to show her the mice he called humanely exterminated, while she questioned his claims about the Doma Family and his siblings. The chapter ended with Utaha realizing that the basement, crime-scene setup, and jammed signals made Sogo look suspicious again.

• Sogo led Utaha to B5, where she saw mice drinking cola, reading manga, and eating snacks in glass enclosures.
• Sogo insisted that letting the mice live comfortably until old age was a punishment because they could no longer hunt, while Utaha argued that it seemed like a reward.
• Utaha noticed a mouse proudly holding up Sogo’s autograph, and Sogo denied that he planned to use the mice to experiment on Umaru’s size-changing ability.

Sogo Doma and his companions teased Mashiro Shiina with Shaqiang, an AI in Sogo’s self-driving car, while Utaha Kasumigaoka grew increasingly alarmed by Sogo’s antics. The car raced toward a rooftop gap with no one at the wheel, leaving Utaha panicking as the others treated the jump as routine.
