Yell

Yell (エール Ēru) is an Aluminum Akikan who came from a sports drink who is owned by Najimi Tenkuji. She's usually cool and composed but she becomes furious when someone tries to insult her owner, going as far as to attempt to kill Kakeru Daichi when he (unknowingly) upset Najimi. She's got sharp vision which was the cause for her being sensitive to moving objects, causing her the urge to play with it. In this aspect and several others, she is very cat-like. Her tail-like hair that twitches when she sees moving objects accentuates this fact. She also loves animals and she has a pet turtle called "Kame". She uses the "isotonic sword" as her cool drink sorcery, which can cut through anything made of organic matter.
