Mahiru commands as Guild Master of Elizabeth Park, directing its operations and members. She operates as a physical-focused midline attacker, specializing in disruption and area control through her combat skills. Her Union Burst, "Elizabeth Combination," delivers substantial physical damage to the foremost enemy while inflicting a 5-second Stun that halts actions and knocks the target back. This ability also deals significant physical damage to surrounding enemies and applies Confuse for 4 seconds, forcing them to attack allies randomly and blocking Union Burst usage.

Bond progression enhances Mahiru's attributes: bond level 2 grants +15 physical attack, with subsequent levels incrementally boosting this stat alongside others. At bond level 12, she gains +210 physical attack and +20 accuracy.

Her maximum stats at 6★ with fully upgraded equipment and bond levels include 53,257 health, 21,792 physical attack, 1,005 physical critical, 924 physical defense, 736 magic defense, 18 dodge, 92 accuracy, and 58 TP recovery rate.
