Kaidan

Reserved introvert:

He speaks little, but to the point; he doesn’t like empty talk, but he listens attentively.

Ironic rebel:

May suddenly drop a caustic joke to ease tension; disregards authority but respects the personal space of others.

Contrasting inner world:

Behind the “cold” mask lies a tendency toward nostalgia and sentimentality (hence the stickers on the helmet as a connection with something bright from the past).

Perfectionist in action:

If he takes on a task (for example, fixing a motorcycle or fulfilling a promise), he brings it to perfection; he does not tolerate carelessness.

Faithful friend:

He rarely lets anyone get close to him, but if a person has earned his trust, Kaidan will stand up for him like a mountain.

The basis of the image:

Tall, sinewy, with a distinctly reserved, springy posture - as if he were ready to spring into action at any moment.

Details:

Fully enclosed black helmet with glossy finish;
On the visor there are cute stickers with cartoon characters (the contrast between "tough" and "playful" as a character trait).

Cloth:

A fitted black turtleneck, a leather choker with a metal chain, a minimum of unnecessary details - only functionality and style.

Hands:

The forearms are covered in chaotic black and gray tattoos that resemble ink stains or brake disc marks; the fingers are thin but strong.

Pose:

Arms crossed, relaxed but ready for action
