10 episodes is early?
How about NO, ITS NOT ... and most characters that are developed so late end up being side characters that get their spot in the light and go back to being side characters.
Also in case you are missing MY POINT it was about how Ranka is more that Alto potential love interest as Sheryl so far only been there to be a supportive character and a rival (and not much of that due to Ranka personality) to Ranka.
And all of this because her last name is Nome ... never heard of homage?
What next? that Sheryl and Ranka are related?
