Kiruko and Maru have taken Nata to guide them to where Yamato might be located (the island facility that all the kids were at in the past) but are currently on a detour in Osaka to look for the Funayama orphanage that Kiruko grew up in after it moved there. The orphanage is run by Tohru, the man in the first half of the flashback this chapter and last chapter who's been doing coverups and assassinations for politicians. Last chapter his flashback portion was in 2019 while Robin's was in 2024, and now both flashbacks are just prior to the Nibiru impact. Since Robin was involved in running the orphanage and possibly its creation we should be finding out how that all happened soon, how they met, and how it'll tie into what's going on in Osaka currently with the new heaven gang and the people Kiruko and Maru just met.
