Kongou's method of greeting

Kongou-san has a strange way of greeting me.

Hey, Bukki! Good morning!

Kongou-san?!

Sometimes she kisses me on the mouth, which she tells me is her style.

Lately her "greeting" has began to make me feel really weird.

K- Kongou-san

Happens every morning.

Is this really a greeting?

Hey Hiei, let's go on a misson together!

Oh, Onee-san looks so happy today!
