Tsutsumi's main offensive Trigger is a shotgun loaded with Asteroid bullets. It has high firepower and, due to the number of bullets fired at once, it is difficult to avoid at close range, but its accuracy decreases at mid-range. When Bagworm or Starmaker are not required, Tsutsumi can double his firepower by using two shotguns instead of just one.
Starmaker places a marker on the location hit by a bullet, making the area of impact clearly visible and detectable for the user and their allies, also enabling stealth combat. Thanks to its wide bullet spread, Tsutsumi's shotgun is a particularly good match for this Trigger.
