My impressions when I first played it

— I wonder if Onee-chan is alright... — I have to find her quickly... — I wonder if Onee-chan's leg hurts...

— I wonder if Onee-chan is alright... — I have to find her quickly... — I wonder if Onee-chan's leg hurts...

The kind younger sister. She dedicated herself to finding her older sister, who has a leg disability, without a single complaint. The nuance is that she never gets angry, even when her older sister disappears many times.

My impressions after watching every ending

The younger sister with the homing instinct. She's doing her best to get her older sister back. She's so worried about her older sister that it feels like she may lose her mind. It's not a matter of being "kind" or something: her head is full of thoughts about Onee-chan. It's heavy!
