Well, in ToAru Universe, every single female belonged to Touma, with exceptions of Kuroko, (probably) Misaka Worst and Last Order. This is the very point at which Touma finally managed to include Last Order in his harem, with both versions of Accelerator... or should I say, IN THE PROCESS OF INCLUDING both versions of Accelerator... I don't really know who was the primary goal, if he's not like "Gotta catch'em all" after all.
All that aside, the picture is breathtakingly amusing, and the artist is really high, and is really mighty. I hereby thank the artist for this picture. Good job.
