While still incomplete, Chimera Shadow Garden floods the area with thick fluid shadows. This grants the user the ability to manifest multiple shikigami, as well as advanced manipulation of all available shadows.
With an enclosed barrier, Chimera Shadow Garden traps the target inside the user's shadow, recoloring the entire space into a negative palette. It also conjures a large object that resembles two columns of a spinal bone with bow-shaped ropes tied and roots attached to it. This disappears soon after the initial casting of the domain.
Anyone standing in the shadow will have to reinforce their feet with cursed energy or risk falling into the abyss. Within the liquid-like shadows, there is no buoyancy, resistance, or oxygen. Anyone who has dropped into it will fall indefinitely.
Megumi first manifested Chimera Shadow Garden in a battle by freely imagining himself going beyond his limits. The activation of this technique used nearly all of Megumi's cursed energy, resulting in physical backlash. This coupled with Megumi's inexperience resulted in an improper Domain Expansion without a complete barrier or a must-hit effect. Even so, the domain was effective enough to enhance Megumi's Ten Shadows Technique to a greater degree than normal.
The floor of flooded shadows can quickly reshape itself into black toads that can grab onto Megumi's target. He can also surf using these frogs to move across the waves of shadows at high speed. Multiple versions of Nue can be created as well, capable of flying around and attacking the opponent rapidly.
Aside from creating more shikigami, Megumi's manipulation of shadows improved greatly as well. After suffering what appeared to be a fatal blow, Megumi was able to fake out his opponent with a shadow double. In order to finish the fight against the Finger Bearer, Megumi used his amplified Ten Shadows Technique to hide in the curse's shadow with Divine Dog: Totality and dealt the killing blow from behind.
During the Shibuya Incident, Megumi used Chimera Shadow Garden to enter Dagon's Domain Expansion. He entered through a large explosive geyser of shadows that could expand to his allies. This allowed Maki access to the weapons cache within Megumi's shadows, or more specifically: Playful Cloud.
The explosion of liquid shadows maintained its shape within Dagon's Horizon of the Captivating Skandha as a tunnel of twisting shadows Megumi was able to emerge from. Entering a Domain Expansion tug-of-war with Dagon, Megumi effectively nullified the guaranteed hit normally gained with Domain Expansion. Dagon attempted to crush Megumi's Domain by attacking directly, but the Toads provided footing for the other Sorcerers to use in order to protect Megumi.
Rather than try and fight Dagon's more refined Domain Expansion, Megumi was using his to create a hole in the curse's barrier. This quickly used up most Megumi's cursed energy, causing blood to flow from his nose as backlash like the first time he used it. Megumi's intention was to use this as an escape plan for all the sorcerers trapped inside Dagon's Domain. However, he accidentally let in Toji Fushiguro from the outside. The hole closes shortly after, leaving Megumi unable to open another hole.
While fighting in the Culling Game, Megumi considered using Chimera Shadow Garden when he found himself outnumbered by Reggie Star and Iori Hazenoki. However, with his domain still incomplete, it would've been foolish to cast it without being able to trap his opponents. Instead, Megumi was able to separate Reggie from his partner and lure him into a spacious gymnasium he deemed a perfect fit for his domain. Unable to use barrier techniques very well, Megumi forcibly enclosed the barrier by converting the gymnasium into his domain and trapped Reggie inside.
The domain was still incomplete and couldn't incorporate a guaranteed-hit function, but it powered up the Ten Shadows Technique's overall potential to 120% of its maximum. Reggie didn't realize the domain didn't have a can't-miss attack and attempted to counter with Hollow Wicker Basket. That technique targets barriers rather than cursed techniques themselves and was unable to stop physically manifested toads from binding Reggie. The increased performance of the Ten Shadows Technique allowed Megumi to summon two clones to fight beside him. They were able to move in and out of Reggie's shadow as well and the three of them quickly overpowered and pummeled their adversary.
Reggie used Megumi's shadow against him by summoning three cars and dropping them into the domain. Megumi can keeps items in his shadow but he must bear their weight. Reggie immobilized Megumi with immense pressure and destroyed his clones. However, Megumi turned the tables on Reggie by using the shadows above Reggie to drop Max Elephant on top of him, turning their fight into a contest of bearing weight.
While holding Max Elephant, Reggie realized Megumi wasn't dispelling his domain because anything the shadows could be trapped inside after its gone. He decided it was a bad idea to drop into the shadow voluntarily to activate his cursed technique and finish the fight. The possibility that he could be trapped in the shadow after Megumi died was too risky for Reggie. Instead, he tried to withstand Max Elephant's weight while activating his cursed technique, only to lose his footing and drop into the shadow. He fell through the shadow without any resistance and began to lose consciousness before commanding one of the cars he dropped into it to take him back to the surface. Reggie attempted to finish Megumi off by dropping a small wooden house into the shadow. Megumi dropped into his shadow and dispelled the domain so that the house broke the floor and dropped both combatants into a pool in the basement below.
