Rina is a character from the Blood On The Battlefield series made by DeviantArt user MajorKrystalFan. She acts as a minor hero in the story.
Rina Sachikawa came into the school because her village of ninjas thought she was "much too incompetent" to train with them anymore and sent her there to toughen up. However, she had proven extremely dominant in her training and in sparring, especially when there was a surprise session with Satoshi.
Her hair is brown, tied in pigtails. Her face is made up with pink eye shadow and lipstick.
She wears a black ninja gi with wrist bands, a scarf, kickpads, a kunai belt over her chest & straw sandals. She also has a half-sleeve tattoo of sakura flowers on her left arm and blue angel wings on her back.
Rina is full of energy. She loves going out and trying new ways to get from point A to point B by any means necessary, doing her best not to rely too heavily on her teleportation techniques.
Teleportation - Wherever she throws her daggers, she can directly teleport to them.
Superhuman Balance - Rina can balance on anything, even run on her hands.
Hydrokinesis - Through her Gem, Rina can unleash pillars of water at her opponent(s), up to 5 at a time in succession.
Ergokinesis - Rina can create an exploding ball of blue energy in her palm.
Rina's style is based around her clan's style of ninjutsu, consisting of rapid attacks, sharp slashes and using the arena to their advantage.
