Crossovers are always the best. Gonna go for a canon character, eheh.
Name: Hibiki Tachibana
Age: 16
Gender: Female
Appearance: Civilian form and
Symphogear FormWorld of Origin: Senki Zesshou Symphogear
Personality: Hibiki is a kind-hearted, cheery person though a bit aloof and zoned out sometimes, especially when she's focused on a particular train of thought. Her hobby is helping others and she loves food. Determined to always look for the best in everything, Hibiki is an optimist that wishes for things such as world peace. Though an idealist, she is also direct and is willing to actively fight for such ideals.
History: Hibiki's story started two years ago when a particular concert was crashed by extradimensional invaders dubbed as the Noise. Being saved the previous user of the Gungnir Symphogear, Hibiki then went on to unknowling carry a fragment of a fragment of said Relic inside her until she was once more attacked two years later and discovered she was now capable of using said Relic. After much training and battles while under contract by the Japanese government, she gained enough power to truly protect those she cared for as well as the entire world from the menaces of the Noise and the villains who direct them.
Abilities: Hibiki is an Attuned, or more specifically a girl who can commune and synchronize with Relics, legendary weapons/objects from humanity's legends and myths such as Durandal or Excalibur. In her particular case, Hibiki is the holder of a fragment of the Relic Gungnir, which she uses as a power source for her Symphogear- a battle suit created through black box technology to fight the enemy of her world's humanity, the Noise. Clad in the Gungnir Symphogear, Hibiki gains characteristics that many magical girls get such as vastly uprated speed, strength, endurance, and reaction times. Due to not having an Armed Gear (the true weapon system of the Symphogear system), Hibiki compensates by rerouting power that normally goes to said weapon to the armor portion instead, resulting the ability to channel power through her boots and gauntlets to weaponize it and enhance her Chinese martial arts techniques with either pistons or rockets to deal focused damage into a single point or fire off literal rocket punches and explosions. She is also protected from beings that instantly convert her physical make-up into another substance and the heretical technology lets her harm entities out of phase with regular reality. Besides these points, Hibiki has the power of "holding hands" due to her insistence on not having a weapon which lets her help stabilize/redistribute other people's burdens/power through herself as the focal point into a giant combination attack such as a rainbow tornado or a giant rocket fist.
