Meiya is the sole heiress to the Mitsurugi Group, one of Earth's largest and wealthiest corporations. She's best known for her unwavering commitment to Bushido and her exceptional skill in melee combat—particularly with blades. Growing up sheltered in this privileged world has made her somewhat out of touch, though she's surrounded by overprotective attendants and unlimited resources that usually help smooth things over.
In Extra, she famously wakes up in Takeru's bed and announces they're meant to be together, setting off the game's romantic chaos. Her privileged upbringing constantly lands her in awkward or difficult situations despite her best intentions.
By Unlimited, Meiya has become one of Takeru's fellow cadets and is clearly the squad's most talented fighter. Her talent catches official attention too—she's assigned a Type-00R Takemikazuchi as a personal gift from the Japanese Shogunate, and an entire Imperial Royal Guard detachment watches over her. These details hint at something bigger going on beneath the surface. Though her background is completely different here and she's far more worldly and composed, her core personality—that fierce sense of honor and righteousness—never wavers. She's constantly torn between her duties as a soldier and her obligations to the Japanese people.
In Alternative, Meiya remains essentially herself but gets significantly more development. Her personal history expands, her character deepens, and she becomes much more central to the story.
