i really like the chapter in the third arc that beta and alexia's arguing with each other, beta flexing her boobs, had my dying. So basically i acutally like her appearance and personality, but i can't really go against beautiful black haired girl, beautiful onee-san type of characters that's why claire's my number 1. As for alexia, i came to like her when i saw this illustration in third arc
