Looking at the heroine from various angles
Natsu: Karin? Very powerful, even though he is smaller than us, he is stronger than us all.
Lucy: A friend worth making, very proud and cute.
Wendy: Sister Karin is very strong and always protects me.
Erza: A strong person, very cute, who always saves us at critical moments.
Gajeel: Her smile is very common, typical of a sinister person.
Gray: I like her. I fell in love with her the first time we met.
Zhu Bian: Love rival, love rival, love rival, love rival!
Laxus: Stubborn as hell, and very bold, but I just like this kind of blue-haired girl.
(Tang: Since there are too many people in Fairy Tail, I won't list them one by one.)
