Why didn't Diga fight back against Ksenia Gaulias Jova Camilla?

Nostalgia According to "Nexus Altman", in the 36th episode, 17 minutes, when Nexus was knocked down, Gigi Zeyou used the power of Nexus to wake up Diga. After Dijia appeared, he didn't fight back, because he missed his old love after seeing Ksenia Goyajova Camilla. The name "Nexus" symbolizes the meaning of connection and bond, just as the power of light was successively inherited by photographer Ji Yazhun, Prometheus' companion of a thousand young trees, Nagi Saijyo, vice captain of the night raid team, and Kazuki Komon, a member of the night raid team. Numerous fetters also make the power of light constantly evolve and recover in the process of inheritance, and finally leave the earth with the attitude of Noah Altman after destroying the dark zaki.
