Aishuku sees the grenade land near his feet on the stairs and pays little attention to it. Knowing that he has both flare compensation and thermographic vision, the possibilities for smoke or flashing from the object hindering his sight would be minimal at worst and non-effective at best.

<<We need this guy alive, so if you can avoid shooting him in a vital area, that would be awesome.>>Aishuku then races past the grenade, up the stairs, hoping to make it to the 5th floor landing so he can come face to face with the unknown individual. When he gets a clean shot, he wastes no time in firing at the guy.
