actually I think this is his power. It is called Break Seal - "Open Sesame."
He has the "capability to open anything and everything". Phrased similar (あらゆるも[ry]) to Flan's (to destroy absolutely anything and everything), Eirin's (to create any and every drug) and Yukari's (to manipulate any and every boundary).
So, yeah, broken. Things he can open include non-physical stuff like the minds and hearts of others (gee, wonder what would happen if he meets Koishi). The main weakness of his ability is that he can't closes what he opens (well, unless it's something simple, like a jar lid), and has a habit of activating subconsciously (which is why he's Casanova incarnate).
And well, he could in theory pull off tricks similar to Yukari (or Seiga), but since he can't close the portals he opens, they will start to backfire on him quickly.
Edit: Hmm... it's long overdue for him to start parodying that Commodore Perry scene from Zetsubou Sensei.
He's a Mary Sue from Mary Sue planet with the Mary Sue power to Mary Sue himself into every Mary Sue situation.
The artist treats the entire of other people's franchises like his own personal wankrag and views anything with a vagina as his personal property to satisfy his base impulses.
...why did Saki's outfit look unusually similar to what Hecatia would wear in LoLK, which was fully released 4 months after this picture?
And since we do...Loli spotted!His beloved two daughters have come to visit him at the naval base.Saki, plainclothes ver.Ou!They say we should "unwind and go outside for some fun sometimes," and since we do have some free time...Your punishment is to take it easy for two-to-three days.I'd told you that you can't come here since things can get dangerous...Geez...TMPTMPTMPTMP26.5 Knots
