More Rinha Lore

Rinha hasn't sung at full power since the end of their first year of middle school, so she's been holding back since that time. Apparently this was also the last time that Rinha found idoling to be fun. Misuzu realized this, but didn't intervene as she was enjoying unit activities. She was the first of the trio to have her dream achieved (possibly not of her own volition), coinciding with the the removal of target of adoration which I assume is her sister. This may involve surpassing whatever expectations she placed on that image. Misuzu wishes she could have said back then that Rinha could look up to her. Because she's more talented and skilled than her (this is where the title of her scenario comes in).

Misuzu thinks that it would be difficult for even her to win against the Rinha from that time, but of course Rinha lost motivation and quit being an idol once Syngup disbanded and isn't at peak.

Misuzu says Temari is a true idol and would definitely defeat Rinha and Kaya too. Temari does go on to defeat Rinha in the next commu.

Misuzu knows Rinha has been acting as a character which doesn't suit her and wants her to stop as Temari is impressionable and copies her (misunderstandings included).

Also Temari's crying face is her greatest weakness and she'll do anything when that happens.
