Midorikawa uses this Trigger to maneuver around the battlefield in the air and to increase his speed without warning, surprising the opponent. He is widely considered a very skilled user. He can utilize Grasshopper effectively even indoors.
Pinball (乱反射,Pinbōru;?, lit. Diffuse Reflection): After creating multiple platforms around the opponent, Midorikawa bounces from one to another at very high speed while slashing at the disoriented target with Scorpion. Between Midorikawa and Yūma, Kō Murakami regards the former as the better user of this technique.
Oki uses this Trigger to quickly leap tall buildings to reach his sniping position. It is also very useful to retreat or relocated once spotted, although it is not as effective in long-distance crossings. He first used it in Chapter 152.
Okudera utilizes this Trigger to gain an advantage on his opponent through mobility. It allows him to fight effectively even on terrains that would normally impede movement. He can also use it to assist Koarai.
Katori is able to utilize this Trigger well enough to keep up with Yūma and fight him in mid-air, remarkable feats both. In need, she can propel herself by placing her palm on a platform instead of her foot, which allows her to move sideways more quickly.
Yūma was able to employ Grasshopper in combat with great efficacy the day after it was explained to him, possibly thanks to his practice with Bound, and soon after became capable of fighting while in mid-air. Not only he quickly mastered its basic applications, his originality with this Trigger earned him Kōhei Izumi's admiration. His small build gives him an advantage over heavier opponents in aerial combat. Yūma can use this Trigger for quick dodges even while airborne, for hit-and-run tactics, to build up momentum before a strike, and to outmaneuver the enemy, cutting off their retreat. He also utilizes it to rapidly cross the map in order to assist teammates in need, as well as to distantiate himself from troublesome foes, which he primarily does by jumping upwards. While this generally allows him to get out of Attacker range, it makes him an easy target for Snipers. By feinting the jump, however, he can catch the opponent off-guard. In addition, Grasshopper compensates for any impairment to his mobility, such as injured legs or terrains that make walking difficult. In need, he can also propel himself by touching a pad with his hand. Yūma's less conventional applications of this Trigger include using a platform to hurl debris at the target, to boost an ally and to launch an enemy in the air, where they are vulnerable to subsequent attacks.
