Why can Kinosaki keep up with Gero's sprint? At first I assumed sword guy is carrying her, because he wasn't immediately shown among those staying behind, but as later revealed that isn't the case. So she successfully rushed past bug and needle user and caught up to Gero running full speed?
A pile of Hikarus, huh? Doll user and Gero grandma were together for 127 years, so it appears as if they were very busy producing grandsons.
