Black swordsman

A man...
Who is too calm...
In front of too many enemies...
Now one of his name is revealed...
Someone heard the name.

The beater of the front line in the assault team?
The solo beater on the 100th floor...
I have 2 things in my name on 100th floor.
Which one do you want to know?
The explanation of more knowledge of that world he lived in that online...
I tell you... I know more of this world than you...

Orange? Sure. What do you think?
Can you risk it?
Your life?
