Impact is Makoto's weapon.
Makoto's tonfas can charge from Power Level 1 to Power Level 3 to help deal more damage to Makoto's opponents. Her damage output is multiplied by the implemented level (i.e. level 1 is normal, level 3 being triple). They, while not confirmed to be a Sealed Weapon, have some magical properties and can emit small projectiles as well as magnify Makoto's already overwhelming strength.
