In a sense, Rengoku Kyoujurou faced the most troublesome demon.
In terms of difficulty, the Half-Heavenly Dog was much more challenging than even Akaza, the Upper Moon Three, who was ranked just a notch above it.
Every demon has its own characteristics and features, which are their most unique abilities and skills.
Take the Lower Moon One, Nightmare, who planned the Infinite Train Incident; it was a demon of sleep, capable of forcibly inducing dreams, and even a Pillar could inadvertently fall victim and die tragically.
Then there was Akaza, Upper Moon Three, a demon of combat, whose martial arts and Blood Demon Art were all designed for direct confrontation with the enemy.
Compared with these two demons, the Half-Heavenly Dog was even more bizarre and more troublesome.
It was a demon of clones, fighting with a Blood Demon Art called "Concrete·Split" at its core.
