Itsuwa  

, 五和

An Amakusa Catholic girl who harbors romantic feelings for Tōma but is too shy to express them. She has accompanied him on multiple occasions to Italy, France, England, and even became his caretaker in the 16th novel. During the attack by Acqua, she failed to protect Touma and tried unsuccessfully to heal him with magic due to his Imagine Breaker. After Touma was sent to the hospital, she felt despondent but was rebuked by Saiji who urged her to look forward to the future when Acqua would attack again and focus on proving her worth to Tōma. In the rematch against Aqua after Tōma's near-death experience, she displayed a sudden change in personality, becoming full of tranquil fury that even changed the way she spoke. She performed a "Saint Destroyer" during this battle and caused Acqua to lose his "Divine Mothers Mercy." Her weapon is a Friulian Spear which can turn into a symbol of a "Thousand Years Tree," making certain magic spells more potent over time. Additionally, she can perform Nanasen (七閃, "Seven Flash") by manipulating her spear and steel wires like Kanzaki Kaori.
