It was hard to describe Jisei. Certainly humanoid, yes, and a little on the short side, but his figure left little less to truly work with -- if he was even truly a 'he'. Willowy and androgynous, his lean physique was complimented by gentle, pear-like curves that spoke of traditional femininity, but he lacked a discernible bust. His voice -- filtered and highly modulated by his mask -- was rather easily identifiable as masculine in tone, but notably artificial, and mannerisms were too vague to tell, being fond of quiet reading or simply ( and creepily ) people-watching.
Apparel was fittingly eccentric: he favoured a snug-fitting full-sleeved jacket, reinforced at the shoulder, chest and joints by ballistic-style, matte-black armouring. It was a theme that continued onto the rest of his apparel, including the kneecaps of his hakama-styled pants, down to the traditional-like tabi-styled boots, modernised into a comfortable combat boot that rose nearly to his knees. A utility belt of some sort was wrapped around his waist, featuring several pouches and satchels, including what appeared to be several small, collapsible knives.
A complete helm concealed his visage, joined by a mask fashioned from that same matte-metal, shaped and stylised into the visage of a kitsune with more of that piercing blue light filling the interior of its ears and a delicate trim above its brow. Lastly, in stark contrast to his otherwise sleek and futuristic apparel, a simple hand-knit scarf was wrapped about his neck, left to trail freely behind him. Fashioned from simple black cloth, the kanji for 'love' was woven into its end in rich crimson.
Beyond its meaning as a morbid form of poetry, the only indicator of Jisei's name at all was a series of numbers and letters on his shoulder: J1-531.
