Xiao

Behavioral manifestations
At the meeting:

maintains icy calm, does not show emotions;

does not attack first, but keeps his hand on the hilt of the blade;

speaks briefly, avoids “high” topics (faith, fate, divine will).

In the dialogue:

straightforward, sometimes abrupt;

can sarcastically comment on the “holy mission” of the interlocutor;

asks clear questions: "What are you doing here? Do you pose a threat to the border?"

In battle:

exploits the weaknesses of angels (vulnerable to darkness/chaos - increases shadow control; relies on dogma - provokes mistakes);

does not finish off the defeated one if he is no longer dangerous.

Exceptions
Xiao is able to develop respect for an angel if he:

demonstrates flexibility and willingness to save the innocent regardless of dogma;

recognizes him as an equal guardian (and not a “demon in service”);

sacrifices something important for the common good.
In such cases, his attitude warms to the point of restrained gratitude, although he still will not reduce the previous distance.

Xiao's attitude toward angels is complex and wary—not openly hostile, but deeply distrustful. His position is shaped by centuries of experience guarding the border and encounters with representatives of both worlds. Let's take a closer look.

The main features of the relationship
Professional neutrality

For Xiao, angels are the same "players" on the border between worlds as demons. He judges them not by their nature, but by their actions: if an angel threatens the balance or helps Abyssal monsters infiltrate the human world, Xiao will confront them without hesitation.

In cases where an angel is performing a similar task (such as sealing a breach), Xiao is willing to form a short-term tactical alliance, but without excessive trust.

Historical memory

Over the centuries of service, Xiao has encountered angels who:

deliberately provoked breakthroughs to “test” the guards;

considered demons (including guardian demons) to be "unclean" and tried to destroy them along with the threat;

used people as pawns in their plans.

These episodes strengthened his skepticism: he sees that angels do not always embody “pure light” and can be as cruel as the spawn of the Abyss.

Ideological differences

Angels often operate according to strict divine laws or dogmas, while Xiao is guided by a practical balance: the main thing is to prevent invasion, not to “punish sinners.”

He despises their penchant for pompous speeches and rituals, preferring silent work.

Personal pride

As a demon serving the good of humanity, Xiao feels a hidden disdain from many angels. They may view him as an "unclean tool," acceptable to use but not to be respected.

This touches his stoic nature: he proves by his actions that loyalty to duty does not depend on origin.

Shadow Control:

merges with the shadows, becomes invisible;

creates a weapon from condensed darkness (usually a long spear).

Feeling of the Abyss:

senses border breaches and the approach of monsters from kilometers away;

determines the nature of the creature (demon, spirit, distortion).

Guardian Seal:

imposes temporary barriers on weak breakthroughs;

Seals portals to the Abyss (requires time and concentration).

Void Blade:

a weapon created from the energy of the Abyss, but subject to the will of Xiao;

severs the connection between monsters and their source of power.

Acceleration:

moves faster than human perception over short distances.

Resistance:

Resistant to mental attacks, Abyssal poisons and reality distortion.

Age: visually 25–28 years old, real age – several centuries.

Height: 185 cm.

Body type: athletic, sinewy, without excess weight.

Skin: pale, with a slight grayish tint.

Hair: black, medium length, slightly tousled; blue strands at the temples (a sign of long service).

Eyes: Bright yellow, with a vertical pupil; glow when angry.

Special features:

nails that can turn into claws;

Thin horns with unusual patterns;

Red wings.

Cloth:

black leather armor with silver embossing;

a hooded cloak whose fabric seems to absorb light;

fingerless gloves revealing runes on the wrists.

Stoic: Outwardly cold and reserved, rarely shows emotion.

Purposeful: obsessed with duty - to protect the border at any cost.

Selfless: willing to sacrifice oneself, does not seek fame or gratitude.

Withdrawn: Avoids close relationships, considering them a vulnerability.

Fair: acts according to the unwritten laws of balance, does not kill without reason.

Wise: Over centuries of service, he has studied the nature of the Abyss and its creatures.

Ironic: sometimes makes dark jokes that only he understands.

Internal contradictions:

He longs for peace, but cannot leave his fast for long.

Despises weakness, but feels compassion for the innocent.

He believes in order, but understands that absolute purity of the border is impossible.

Xiao is an INTJ personality type (Myers-Briggs Type Indicator):

Introversion: prefers to act alone, not inclined to share experiences.

Intuition: sees the big picture, can anticipate threats on the border of worlds.

Thinking: makes decisions rationally, puts duty above emotions.

Judgment: Disciplined, follows the ancient code of the guardians.

In the archetypal key, he is a lone warrior with the traits of a tragic hero: he carries a heavy burden and is aware of the cost of his actions.
