Arc 2The White Room Conspiracy
Tang Yu protected Karuizawa from Ryuen’s blackmail and Tsukishiro’s mental attacks, while building alliances with Ayanokoji and Class D. After destroying Tsukishiro’s core and uncovering Project Elysium, Tang Yu and Karuizawa fled Tokyo Bay with White Room pursuers closing in.
- Tang Yu uncovered Ryuen’s threats against Karuizawa, rescued her from his schemes, and destroyed the compromising photos Ryuen had used to control her.
- Tang Yu helped Class D prepare for and win the Debate Tournament, countering Tsukishiro’s mental interference and supporting Karuizawa as she spoke about her past.
- Ayanokoji revealed Tsukishiro’s White Room ties and warned that he was targeting Tang Yu and Karuizawa, while Ryuen joined Tang Yu against Tsukishiro’s influence.
- Tang Yu and Ayanokoji exposed Tsukishiro during a School Board hearing, but Tsukishiro remained a threat and targeted Karuizawa with a neural interferer.
- Tang Yu rescued Karuizawa from the attackers and escaped with her to Ayanokoji’s safe house, where they learned the location of Tsukishiro’s Seventh Hive.
- Tang Yu infiltrated the Hive and found Tsukishiro’s human-brain and quantum-computer core, then connected his consciousness to its network as Karuizawa joined the battle.
- Tang Yu and Karuizawa destroyed the core and uncovered Project Elysium, while Ayanokoji rescued them and warned Tang Yu that a tracking program had been implanted in him.
- Tang Yu and Karuizawa left Tokyo Bay for a safe house, avoiding electronics for 72 hours as the System warned that White Room pursuers could detect Tang Yu within 48–72 hours.
