Perios  

Jesse Blue, ペリオス

Jesse Blue, who had distinctive blue-green hair and a sarcastic personality, was an exceptional cadet at Cavalry Command until he developed feelings for April Eagle during a training session. However, when April didn't reciprocate his affections and accidentally humiliated him in front of the other trainees, Jesse became resentful towards the Star Sheriffs. He believed that April's love for Saber Rider was the reason she rejected his advances, leading to a personal grudge against the latter.
