[Y/N] POV

"[nickname] look, look! I found this thing in the hallway!!" Tsukasa yelled like a child.

[Y/N] flew forward and look at the device. "We should bring it to check on it!" They siblings went to the broadcasting room which is own by the club member in there including Tsukasa.

They enter the room and put the device on the table. The device is a box-like thing with eyes and switch behind it.

"Look, it have a switch here." [Y/N] turned the device around and show the switch to her brother.  

"Let's turned it on!" Tsukasa exclaimed. He turned the switch and smoke came out.

"We need to be careful with this thing." Tsukasa held [Y/N] close like an older brother will do. The smoke cleared up so the siblings could look clearly.

The two appear in the middle of an unknown place. Tsukasa is surprised that he's not in school while [Y/N] is confused.

"How did I leave the school?" Tsukasa said. 

"Not again!" [Y/N] said.

[Y/N] told her brother that their in another universe which she had went last time. Tsukasa listen and wonder around the place since it is an unknown place.

"Tsu-nii! Hold still." Tsukasa turned around and a sticker is stuck onto his head a while later he stop floating and he's wearing his old clothes like how Amane does.

"Woah! Is this how Amane turned back to human?! Cool!" he exclaimed. [Y/N] and Tsukasa went to a nearby abandoned building to stay there for the night.

[Y/N] summon her bag and pulled out a tent so the two can sleep there.   

------------The next morning---------

[Y/N] and Tsukasa are making the building home so they used the things like paint, brooms, windows, etc that [Y/N] took out from her bag.

The building went from this:

to this:

"We're done!" [Y/N] said after the they finished their work.

"Good thing you came prepare [nickname]! Otherwise, I would've to sleep at the streets." Tsukasa hug [Y/N] like a proud brother would do.

"We should go to a school so we don't look sus." [Y/N] took out a map that she took during their trip to the building the day before.

She lay out the map and Tsukasa point at a spot where PK High School is located. "How did you know there's a school there?" she asked.

"Koku-joudai helped me check if there's any school that is nearby and this school is the one!" he said proud of his work.

"Then it's settle! We'll transfer there tomorrow!" [Y/N] said. 

Tsukasa and [Y/N] had already look like a teenager so they both went to the school, finish the things that they need to transfer and return home.

"[nickname]~ I'm hungry~" the older whined. [Y/N] had went to the store and start cooking for her dear brother.

She put the food on the table before Tsukasa snatch it and finish it in the blink of an eye. They both went to their room and rest before the day come.

Little do they know, a pink-hair boy just happen to pass by.
