To Your Eternity 22

Kaibara has captured Tonari and Bon, and are holding them behind security so tight not even Fushi can break in. Meanwhile, the Captain closes in on Adey and the doll. Fushi and friends set out to rescue their comrades, but Andy attacks using a fearsome new "mode," and Bon sneaks into Kaibara's secret headquarter, all alone. There, he learns the twisted true nature of this future world. This is a story about making peace with the past.
