The art is amazing and the characters are interesting. Now if only this doesn't come out every 3 months or so it would've been perfect.
I really like how all the Saber faces have distinct personalities and different ways of handling situations. Artoria kills her enemies with honor and is calm yet doesn't hold back her words when talking to Shirou. Makes sense because she was a king, she had to make and command her men with tough decisions. Okita is very brutal when it comes to killing but very compassionate and understanding of her master's understanding on the situation.
But the one thing all Saber faces share in common is that they love their masters.
Artoria, Mordred, Okita, Nero.
