There sure seems to be quite a surge of Heart-Throbbing Koakuma on Danbooru recently. A search for Koakuma returns like six or seven images of it.
On a side note, I really do need to watch (the rest of) this series and find out why she's holding her own arm (Assuming it really happens because of the spoilers tag?).
The surge is due to the rest of the series being rapidly translated finally after only the first three were available for a good long while. Part 9 translation should be up this weekend I hear.
Yeah, word is Saturday part 9 will be translated. Heh, Last night I decided to see what the fuss was about this series. I frowned with grimace at the artwork at first, expecting something simple and light-hearted to match. I watched it with puppy eyes and rainbow thoughts.
...I was not prepared.
To comment on the picture, I wonder if Koakuma is the most dangerous person in the story now, considering her ability.
