Mikado Ryuugamine agreed to visit Shinra Kishitani's apartment one night to reunite with Celty after some time apart. Upon arrival, he was taken aback by a sizable assembly of the most elite individuals in Ikebukuro, who had gathered for a hot pot party. To his surprise, Mikado found his Raira Academy school mate and friend, Anri Sonohara, among the crowd. Together they sat and listened as their companions shared stories of bygone days, reminiscing about Mikado's childhood escapades with Masaomi Kida, Anri's strong connection with Mika Harima, and Shizuo Heiwajima's first encounter with Tom Tanaka.
