Background: Riku came from a privileged family; not too rich, not too poor, but rich enough to spoil their only son. As such, Riku grew up spoiled and grew to dislike being babied, and that feeling grew until he became rebellious. While he was a good student, he disliked associating with his schoolmates and the hated monotony of his life, he began to dream of traveling and fighting off the zombies beyond the borders of his out-of-the-way island life. He escaped one night and wasn't heard from for a day until a passing merchant dragged him back in. His parents feared that they wouldn't be able to restrain him anymore and sent him off to HS174.
Now feeling trapped in a newer, bigger cell, Riku remains removed from his peers, his restlessness pushing him to get better at everything he needed, be it fighting or survival.
Physical Description: Riku is 16 years old and roughly 5'7" and still growing. His silver hair is cut roughly and reaches past his shoulders and almost covering his eyes. While good-looking, whether or not he knows it, he doesn't care for personal appearances and lets it be. And true to that mentality, Riku's attitude and manners remain aloof and disinterested, and one would be hard-pressed to find him smiling. All-in-all, he exudes a 'look, but don't touch' aura.
RP Example: Another year, huh. Stuffing his hands in his pockets, Riku stared blankly ahead, barely giving the students in his path a glance as he walked by. The corridors were crowded - as it always was during break, and he was careful to avoid most of the congested areas, heading opposite that of the cafeteria.
He had no appetite, not really. Grimacing at the thought of squeezing into those long lines, he made his way higher, opening the door to the rooftop, taking a careful survey of his typical spot.
Good. No one was there. Settling down and leaning against the wall, he tipped his head up, gazing at the blue, cloudless sky.
