So... they sent a copy to make the "sacrifice" for the AI as a bait in order for Asuma could be freed... but the copy instead commiting suicide has found undeleted somehow Piko-chan or rather her copy Sakurai Hinako, basically two AI copies reunited in a game sandbox/Bird Cage...
It would be wholesome if both real Taichiro and Sakurai met in RL, but probably it's not that kind of story...
