Description
Horinuki Masamune stands as the youngest of the Houchou sisters trio. She naturally positions herself slightly apart from her elders, embracing a dedicated support role that highlights her sisters' strengths to others. Academically accomplished, she commands knowledge across diverse artistic fields and maintains a strong fascination with creative professions like artists and performers.

This intellectual curiosity often leads her to weave elaborate narratives from fragmented information, resulting in imaginative tales others frequently correct. Her profound admiration centers on Kuwana Gou, specifically captivated by Kuwana Gou's mature femininity, elegance, and grace. This admiration borders on reverence, prompting heightened enthusiasm in Horinuki Masamune whenever Kuwana Gou is mentioned; her tendency for imaginative exaggeration manifests prominently here too.

Within the Western-style tea house "Meiji-kan," she collaborates with her sisters and other Mitsurugi, continuing her supportive role. Personal preferences include fashion and style, while she distinctly avoids interactions with gentlemen. Preferred gifts align with fragrances and personal care items: perfume, incense, soap, camellia oil, and facial lotion.

In combat, she wields the Water element and embodies the Virtue of Wisdom. An "SR" rarity unit of the "Mow Down" type, her abilities focus on team support. Her signature move, "攻昂ノ掛声," grants a slight attack power boost to all allied Mitsurugi. Her ultimate technique, "流華繚失," executes a rapid series of strikes. Leadership skills "Vitality Mastery" and "息吹ノ心得" provide minor maximum HP increases for the team. Progressing through her Blooming Ability panels enhances these supportive capabilities, improves stats like Attack, Health, Defense, and Luck, unlocks functions such as a Switch Attack, and requires specific upgrade materials like Magatamas and Mirrors at each stage. Her Attack stat grows from 45 at level 1 to 453 at level 80, while Health increases from 40 to 320.

Her speech involves referring to herself as "Watakushi" (わたくし) and addressing the master as "Aruji-sama" (主様). She is also known affectionately as "Nuu" and "Nuu-chan." She was acquired via the "-巫剣エピソード- 銘治乙女鏡〜三姉妹、めいじ館に行く〜" event or the regular gacha pool, released December 2, 2019.
