Contrary to Soul Eater, this manga is about realistic girls with ordinary lives, mostly. Except they live in the SE world and occasionally run across your favorite "eat" characters. But the Eats look different from the outside. A lot more tough and scary.
The story is really about a young weapon who isn't very strong and somewhat shy, thrown in with two more outgoing girls and one potential love interest (boy). Mostly, its just slice-of-life, with excitement provided by Eats in the environment.
In this second volume, Tsugumi finds herself being forced to choose between her two best friends as they both want to be her partner. She hasn't quite caught on that the mysterious boy, hihgly skilled and favored by the Eat teachers, has an ambiguous interest in her. He hints that he wants Tsugumi to be his weapon, or could there be more he wants? What does he see in Tsugumi that others don't see. She's pretty average, though all manga girls are cute, of course.
Just like Bleach, I grew tired of Soul Eater's fighting-manga at around volume 10. Who cares? This story is much more interesting with drama, relationships and hopefully, happy endings.
