It's not much better in her own ending, where we see her grandparents and Rimururu mourning her and her soul also begs them to not grieve. It then goes to happy tears as Rimururu clutches her sister's sword and says "I understand...", meaning this is the moment where she decided to fight on.
Ukyo's ending doesn't help matters. Retconned or not, it's still not easy to see Kei mourning him both as a girl and as an old woman.
The end of the Nakoruru OVA. Specially when Nakoruru speaks to her mother and asks her if she's crying.
Mikoto's ending in Warrior's Rage, when she reunites with her parents, Shiki and Asra... in a vision.
