Soldier's Instinct

It was most easily likened to a soft poke on the shoulder, faint but impossible to miss. Despite how gentle the feeling was, it was still rather annoying to someone like Giroro with such a small fuse and large space bubble. It was like the person poking him was a good friend, so he'd resist a smile. It was unidentified, so he'd resist trying to shoot at it. The contradictions mounted, all over something intangible; the feeling of somebody else nearby, but light and airy instead of the normally guarded down that Giroro was accustomed to.

So he'd look around to get the strange emotion to sit still, and he'd see Natsumi entering the room every time.
