It's [グサ](http://thejadednetwork.com/sfx/browse/gusa/), a common onomatopoeia
for a sound of "stab". It also describes how someone's harsh word sticks into
your heart. It's listed on jisho.org in the form
[ぐさりと](http://jisho.org/word/%E3%81%90%E3%81%95%E3%82%8A%E3%81%A8).

It looks like ワ, too, but ワ does not take dakuten, as you know.
