Mysterious Transferee (Assassination Classroom Reader-Insert)

Math is the final subject and the time is almost up. The students are now facing the final problem. Half of the 3rd years couldn't even make it this far. The other half just arrived in a nick of time but they are already too exhausted to continue to solve it all the way. The only ones that are capable of getting full marks in the time remaining...were these three.

Y/N, Karma, and Asano are each floating inside their own cubes. They are having a bit of a hard time since they are still trying to understand the question. They are armed with a rifle.

Karma and Y/N are still reading the question thoroughly, trying to find a specific detail that can make the question more easy to solve and understand while Asano already attacks the little gun shooting monsters on each corner of his cube.

He knows that when both sides are evenly matched, their attacks meet in the middle. He knew this from attacking one of the monsters that is also attacking him and it did meet in the middle.

He had a conclusion that his domain must be inward and he finally hits the monster. Once a monster dies, a red colored deformed shaped dome starts to appear and he had an idea on how to solve the question.

The red domain that cages the enemies have a flat surface that faces inward and it forms the corner of the cub on the other side, where the monster is located, and there's a small flat surface where two of the domains meet.

Asano further concluded that in order to find his own domain, he needs to find the volumes of all eight monsters and subtract it from the total volume of the cube, and he will find his domain.

He continues to shoot the remaining monsters while he starts to write his formula on his test paper.

Y/N is rubbing her forehead with her left hand while she points her pen to each word in the question until both she and Karma sees the detail that made the question more understandable and much easier.

The both of them thought that it isn't tough math as the two of them floats in the middle of each of their own cube. The cube is just a part of a much bigger cube since the question is only focusing on finding their domain in one cube.

The monsters didn't appear inside their cubes as the both of them realized that since the cube is an atomic crystal, it doesn't end there and it continues outside their cube.

Y/N just looks at one side of the cube while holding her rifle with both hands, her right hand is holding the pistol grip with index finger on the trigger and her left hand is gripping the magazine.

Karma holds his rifle with his right hand on the pistol grip while his left hand touches the one side of the cube.

The both of them realized that from where they stand, each one of their classmates have their own talent inside a domain. And each domain needs to be equal to each other and in order to do that, they imagined a red sphere and divided it into eight parts.

The figure of the sphere divided into parts are shown in front of them.

Y/N released her rifle and it vanishes after it hits the lower surface of the cube. She arranged the parts to be able to fit the corners and to do this, the outer surface or where the curve of the part of the sphere is facing her domain.

The same goes for Karma only that he didn't arranged his but it automatically formed itself. The equal parts suddenly got bigger and covered the corners of their cube and they thought about the parts just a fragment of their classmates talents and in order for it to be equal, it was divided into eight parts inside of their domain.

For them, the domain represents a whole of themselves and one eighth each from other people's fragments.

Karma is looking at a particular part where a (color) haired girl holding a katana while fighting someone that also have the same weapon. He smiled then releases his rifle making it turn into tiny crystals and it finally disappeared.
