fifth volume! what i don't get about this series is why that badass japanese guy wielding the sword (he's name is silver?) speak japanese to revy even though he fully understands that they can't communicate in language, since revy only speak english and that guy only speaks japanese....

Their type can communicate without words...(yet they talk bacause readers arn't their type)

All the characters speak english by default, even though the manga's printed in japanese. It causes some odd mix-ups when a character actually speaks japanese.
