Despite his nervous demeanor, Sasamori is quite skilled. Being in the B-Class #08 unit is a testament to this. Furthermore, he once won four matches against Midorikawa out of ten, although he called it a 'fluke'. He was the first B-rank agent to score a win against Hyuse in a swordsmanship match with Kogetsu, although he lost five times and claimed he had had time to analyse the combat style of the opponent. As part of Suwa Unit, Sasamori fights as an Attacker that utilises Chameleon. He knows how to be an effective decoy to distract the enemy. Tsuji expressed admiration for his understanding of the battle against the abnormal Hydra.
Sasamori is an Attacker who uses Kogetsu. Although he cannot match a Master Class Attacker like Arafune, he has enough skill to repel an attack from one of the Hydras controlled by Yomi, although he was injured in the process.
On top of using Chameleon for surprise attacks, Sasamori has come up with a strategy that does not force him to reveal his presence: he can exploit Chameleon to restrain an opponent with a hold, thus not activating another Trigger and making himself visible, and waiting for one of his teammates to attack the restrained opponent. However, this can be considered a suicidal tactic.
