As a member of a unit in the upper tier of B-Rank, Minamisawa is a capable combatant. His individual score is known to be higher than 8000 points. He fought on equal terms with Kashio, briefly seeming to gain the upper hand due to not being hindered by Osamu's Spider wires. However, his overly enthusiastic personality can lead to him getting reckless and making poor tactical choices, going so far as to ignore the advice of his teammates.
Border's Optional Trigger that renders the user invisible to Radar while activate. Minamisawa uses it to approach the target undetected, but deactivates it before starting combat due to it getting in the way when attacking and defending. He first used it in Chapter 152.
Border's Defense Trigger that enables the user to create a barrier to protect themselves from enemy attacks. Minamisawa uses it to defend from Gunner Triggers while getting close to the opponent. He is also capable of using Full Guard, which allowed him to resist Kurauchi's Salamander without taking damage. He first used it in Chapter 153.
