Aim the Deepest Part of the Different World Labyrinth (WN) Volume 1 Chapter 4.3

Even though Tidus’s body is splitting in two, it is still swinging its blade. Realised that, I came to my sense.
The part of the body that was thrown away in the s.p.a.ce, Tidus breaks its stance.  But I managed to continue to cut its part of Tidus many times by slashing horizontally, vertically and diagonally.
?d.a.m.n YYOUUU=!?
I cut, I cut I cut and CUT!
As the result, many parts of Tidus’s body fall to the ground.
A black gelatinous liquid is scattered and doesn’t go back to the original form.
I beat it.
If this didn’t knock it down, what should I do to defeat it?
However, Just like I feared. I still don’t feel at ease.
A black liquid wriggles and it modelled a mouth and talk.
?Ka, Kahahahaha. Did I get you hope up? You are good at “Speed” “Ability” if that the case, magic, let’s compete in Magic?
In response to its insult before me, I raised my voice out.
?Dia, Shoot your magic!!? 
?Don’t left me out! «Flame Arrow!»?
Dia shoot it with his full power.
That «Flame Arrows»that was just being shooted is unusual than always. Usually it was a flash of light through in an instant but this time is different. The diameter is wide and the irradiation time is long.
Overwhelming heat burns down Tidus’s part of body which was scattered on the ground.
However, I have to make sure to not remain even 1 part of its body. But, some fragments of its body still remaining.
Fragments of its body are crawling around on the ground in order to a.s.semble themselves.
Then, Tidus casts a magic.
?Fuhm, Fufu…, Magic «The sorrow of offspring in the darkness»?
The moment when Tidus cast a magic, a black curtain hangs to my view.
???!? d.a.m.n! what is this! ?
My sight suddenly darkened.
However, the  darkness contrast in the room still has not changed. I know that because I’m using «Dimension». I understood but it puzzled me.
The changed one is me. The darkness that came to my view is increasing.
Feels like I’m inside in the prison of darkness.
However, I could still pick up the information outside of this black curtain. I understood this is not physically wrapped in the darkness but my mental is.
?I allowed you to taste experience in the darkness. My alias name is the one who steals the law of nature of the darkness. However, it doesn’t mean I was called as the one who manipulate the darkness. I’m good at manipulating the darkness inside of people’s hearts. I’m, so called the monster that specialised in the mental attack. Someone who touched my darkness shall meet a despair?
Tidus is proudly talking about his great magic. There is no weakness but thanks to Tidus’s light mouth I can understand something. This is possible to win this battle.
Darkness. Mental attack. Despair.
I dig up my game-like thinking from those words.
?Because you touched me too much?
Tidus pointed out my carelessness.
I feel the black liquid that attaching to my body wriggles. I brush off those things within my range with hand immediately.
While I’m doing so, Tidus managed to finish repairing his body. I can see it even though my view is in pitch black.  Also, I can see the distance between me and Tidus with «Dimension».
I decided to act according to my game-like thinking.
I’m focusing on myself that I’m not a dark figure.
