Seem like Rikka & her sister will have another battle in the next episode .
However , Now its ''To Be Continued''.
This is a heavy episode .
It explain the reason behind Rikka becoming a Chiuuni.
Does the Novel really about Rikka & Shiina's rivalry over Yuuta ?
Because Shiina doesn't mind their relationship and see them as a couple.
On the otherhand,
Does anyone else think that Shiina resemble Asuna Yuuki from Sword Art Online.
