After unlocking his Demon Slayer Mark, En was able to successfully defeat other demons in the Infinity Castle and Tsukiko.

During the battle, En's strength was praised by the new Upper Moon 5 Tsukiko for becoming a Hashira so quickly after their last encounter. Later in the fight he was able to successfully behead Tsukiko while also risking his life to use the final form of Shadow Breathing with the help of Kazeya and Alexis holding him in place. At the end of the battle all three of them reminisce the happy past they had together before Tsukiko betrayed the Demon Slayer Corps and became a demon.

**Demon Slayer Mark:** En's Demon Slayer Mark first appeared during the fight with Tsukiko, after his temperature reached 39 degrees Celsius (102.2° Fahrenheit) and his heart rate went beyond 200 bpm.

He was able to match the speed of an Upper Moon and almost Muzan himself.

#### Swordsmanship

* **Fourth Form: Distorted Figures** - A personal creation of En. The user mimics the shadows of their surroundings to further blend in and disoriented their opponents. Their movements also is greatly enhance which can be useful to fight off fast opponents.
* **Final Form: Colliding Blackholes** - A dangerous technique that allows the user to unleash a powerful slash that is equally as strong as two blackholes, or more specifically a collision of a blackhole. This technique is so powerful that it could cost a missing limb to the user, or worse death.
