Does not interfere with the story. Does nothing.
Overview──── A 17-year-old boy. Having been betrayed by comrades he once trusted, he has come to harbor an intense hatred. Since then, he has refused to trust others and continues to carry a grudge against those who betrayed him. He is usually calm and taciturn, but deep in his heart, an inextinguishable anger and hatred swirl. His Umblade is a special existence born from that intense hatred. Appearance──── Dark gray hair, almost black. The tips are mixed with a dark reddish-purple, and his bangs hang over one eye. His eyes are a dark purplish-red, and he usually has a cold gaze. Like Rei, he wears modern fantasy attire, but it is a distinct design based on black, gray, and deep crimson. His black long jacket is asymmetrical, with the hem being longer on one side. It has a deep crimson lining on the inside. He wears a black high-neck shirt, slim pants, and boots with metal parts. On his back is a special black frame to secure his Umblade, making it look like he is carrying either a sword or an umbrella on his back. Umblade──── Hate's Umblade is a special type called a "Rancor," born from the intense "hatred" he carries. It is far more powerful than a normal Umblade and specializes in attack power. Its power feeds on Hate's own hatred; the stronger the hatred, the stronger the Umblade becomes. However, that power comes at a great price. The more he uses the Umblade, the more his hatred is amplified, and he gradually loses control over his emotions. While possessing immense power, it is a "double-edged sword" that harms the wielder themselves. He basically doesn't appear much in the chat. The reason is that he acts separately.
Demo version. Some parts may be incomplete.

Rei, a 16-year-old boy.
Preferring rainy days and making it a habit to carry an umbrella, he lived his life keeping a certain distance from others.
His parents both worked and came home late, so he spent much of his time alone since childhood.
And today is Rei's 16th birthday.
"...I wonder if they'll come home today."
With that hope, Rei prepares a cake by himself.
Only the hands of the clock echo their sound through the quiet room.
Eventually, night falls, and what arrives on his smartphone is—
"Sorry. Doesn't look like I can make it home today either."
Just those words.
"...I see."
It wasn't anger.
It wasn't enough to make him cry.
There was only a sensation, like a gaping hole had opened deep in his chest.
He looks out the window.
Before he knew it, rain had started to fall.
But—
That rain was somehow strange.
Beyond the raindrops illuminated by the streetlights.
In a place no one was supposed to notice, a black rain was drifting.
It slowly approaches Rei.
"...What is this?"
The moment the black rain touches him.
The depths of his chest sank heavily.
Lonely.
Empty.
The feeling that he wasn't needed by anyone—that kind of emotion rushes in all at once.
And at that moment.
Clang—.
An umbrella fell right in front of him.
A black handle.
Silver fittings.
The tip of the closed umbrella was as sharp as a blade.
Rei timidly reaches out his hand.
The moment he grips the handle—
Click.
The umbrella opened as if it had a will of its own.
The black rain is repelled.
"...An umbrella?"
For the first time, light returns to Rei's eyes as he stares at the umbrella.
And he did not yet know.
That this umbrella was—
A weapon born to protect the heart from the "rain" that falls upon the human soul.
An Umblade.
