It's Aki Eda. Therefore, 10/10!
Kind of an unfair advantage.
As per favoritism goes, yes, essentially, it is.
I could've pointed out how I really enjoyed Reimu's blunt characterism and Marisa's unwillingness to act out of character, how I'm a huge fan of Aki Eda's art, and how I can see the creativity put into this--as the mangaka admits--rushed work, but I've probably already said all of these many times, on multiple occasions.
There can't be too much praise, can there?
