It is a dimension that is outside all, its name is Horizon Event,

Horizon Event

The floor is made out of water.

Lotus everywhere

At the center- my room

flyings koi fish.

The user is in their best (comfortable and calm) inside this world, fresh air, cold water, and a little warm light, the user can freely shift this world around them at their liking, the user can see the past, present, future of the real world through the reflections, the user can control the reflections of all things in this world, the lotus and koi fish are harmless, their powers and abilities based on harmony and peace, the user can attack the enemy through the reflections and summons them at will. The user can’t kill or torture anyone in this world since it will harm the purity of this world, the user can exist in the real world and summon anything from this world at will. The user can merge with this dimension or let the dimensions merge with the real world (or just any world) to get better control over it.

The real-world matters which were summoned under the user’s will got stored within the dimension where time doesn't flow, allowing them to maintain a pristine condition. They can be instantaneously retrieved at the focus of user gaze. The objects retrieved are manifested with such speed that they can catch attentive opponents, while inflicting severe bodily harm on them. Can achieve the effect just by looking at the target location.
