The Art of Sniping Comes Naturally to Him

Mashimo’s prowess in marksmanship is extraordinary, setting him far apart from even the most skilled assassins. His sniping technique includes the ability to quickly assemble and aim his weapon while executing complex movements like jumping backwards. Such precision requires not only skill but also an immense level of training and control.
During the airsoft tournament where he met Shin and Sakamoto, Mashimo showcased his remarkable abilities by swiftly taking out four opponents before his teammates could react. His record-setting performance during his academy days, where he assembled and fired a bolt-action rifle ninety-six times in rapid succession, solidified his reputation within the assassin community, earning him the nickname “Dragoon.”
Mashimo’s resilience also shines through in moments of pain—when injured, he remains focused, sniping targets while enduring discomfort. His primary weapon, a bolt-action sniper rifle, is complemented by his own creation: the Ricochet Rounds. This innovative ammunition allows him to strike enemies hidden behind obstacles, bouncing bullets off surfaces to lethal effect.
Tactical Genius and One-Man Army
His Winged Companion and Tactical Knowledge Makes Him Unstoppable

Mashimo excels in tactical intelligence, demonstrating composure under extreme pressure. One of his unique strategies involves utilizing his pet bird, Piisuke, to scout enemy positions, functioning akin to a reconnaissance tool. However, this comes at a high cost, as feeding Piisuke can run him about twenty thousand yen.
This instinctive killer is adept at adapting to the environment, making swift decisions based on his surroundings and the anticipated movements of his targets. Such skills enhance his effectiveness during engagements, allowing him to tackle challenges without exposing vulnerabilities.
Despite his formidable abilities, Mashimo has clear weaknesses when faced with close-range combat, as his expertise is heavily centered around sniping. Nevertheless, he proves to be a one-man army, capable of dispatching multiple foes, making him an invaluable asset to Sakamoto’s crew. His straightforward personality, combined with a uniquely goofy charm, resonates with fans, solidifying his status as a beloved character in the series.
