@OnlyChelbea Luna's opinion on Ai is fairly mixed, but it depends on whether you're talking about Hoshino Luna or Amemiya Luna. Hoshino Luna sees Ai wholly as her mother and looks up to her, but since her soul retains the memories of Amemiya Luna, Luna will sometimes see Ai the way Amemiya Luna did, which is close friendship. At first Luna was a little weirded out and confused about the whole reincarnation thing, until she got used to it and figured that as long as she knew Ai and the triplets were alright and could stay by her side as well, it was okay. Then Ai was murdered and the Amemiya Luna side of Luna went dormant for over a decade out of grief. Thus Luna lived as Hoshino Luna without the influence of Amemiya Luna until the most recent chapters, as Amemiya Luna is starting to awake again. I'm not gonna say any more, but I can tell you that Amemiya Luna is going to play a bigger role in the future
