Arc 4The Nine Schools Competition
Chiba Yeyou’s CAD work helped First High School’s competitors dominate the opening events, while his Quantum Shatter stunned the competition. After an attempt to sabotage Mari Watanabe’s race failed, First High School continued winning, and the arc left Third High School reassessing its chances against Tatsuya Shiba and Chiba Yeyou.
- Mari Watanabe won the Battle Board heat with help from Chiba Yeyou’s work, then invited him to join her family’s business after graduation, but he declined.
- Mayumi Saegusa won her events with Chiba Yeyou’s calibrated CADs, and he later helped Kanon Chiyoda defeat her opponent in Icicle Destruction.
- Chiba Yeyou took the arena in his school uniform and defeated Yamanaka with Quantum Shatter, which destroyed the ice pillars before they reached the ground.
- Chiba Yeyou explained Quantum Shatter to Mayumi Saegusa and agreed to tune Hattori Gyoubu’s CAD after Hattori asked for help.
- During Mari Watanabe’s Battle Board race, a uniformed man used Spirit Magic in an attempt to cause an accident, but Mari had already surged ahead with Light Energy Pulse.
- Chiba Yeyou, Mayumi Saegusa, and Mari Watanabe suspected outside betting interests and warned the Operations Committee that an infiltrator might have tampered with equipment.
- Tatsuya Shiba’s CAD work helped Shizuku Kitayama and other First High competitors win their matches and secure the top three places in an event.
- Suzune Ichihara agreed to tell the university that Light Energy Pulse was not mature and to register Tatsuya Shiba as the developer of Shizuku Kitayama’s magic, while Third High School’s Masaki Ichijo and Shinkuro Kichijoji recognized First High’s strength.
