@YuriAkuto You have a lot here so I'll have to do what I did for Maou Gakuin earlier.
First one:
"Come on."
You were the bait, and you and your Taikyoku will be consumed.
At the moment of this declaration, the Kamunagara slammed their giant arms down on their respective prey.
Just like being crushed to death by a hammer, this was nothing more than an invitation that leads them to hell.
Calling out their adversary to decide the match with their own hands.
To the Kessenka (血染花) that was clothed, bonded, and pact in blood.
To Yama (閻魔), the beloved and gifted spellcaster of this world.
Guided by the chains of causality, they now come face to face with their karma.
To start, if one had to describe this with a single word, that would be a kaleidoscope (Mangekyō/万華鏡).
In the vast, endless space as far as the eye can see, there were always complex geometric patterns drawn with regularity in the sky.
The mottled and uneven colors were harsh on the eyes, and just looking at them makes one feel naturally uncomfortable.
One may wonder if you could call it chaos with regularity. Perhaps this is what you get when you cut up multiple pictures with scissors and construct a pattern by patching them all together.
It was twisted. It was distorted.
And yet, the unshakable core of it all showed a strange law. It was a landscape of conflicting contradictions and inconsistency...
"That's right. This is my Hell."
With a glance, Keishirou realized that this was nothing more than the inner world of this Kishin.
Something that aches in the depths of their soul.
