Other World Chimera
Speed force

Through experimentation, Tomoka realized a few things about his relationship with speed style. For starters, come up with some theories about what happened during his confrontation with the Kumo ninja. 

“Running numbers, it is impossible for me to replicate what happened earlier with my current amount of chakra. Not to mention that the portal wasn't here before. However, the feeling it gives me is familiarity. Perhaps the portal had been blocked by something before and a smaller force of speed was constantly leaking out. 

Following this line of thought, it was possible that the force of speed had retreated, like a dam filled with water. Then when the blockade was broken, all of that speed-backed force charged towards me. Now that the path is properly open, only the right amount will flow even if I increase the size of the portal. What do you think Kurama”

[I don't know much about all that scientific nonsense but I think it makes sense] To be honest, Kurama isn't very interested in why this problem happened.

“Well, that doesn't matter. I still need to train with him and find out what I can do with him as well as the most efficient way to use him. But before that” With a smile Tomoka started to concentrate. Pushing his desire into his mindscape, he began to reshape it. 

From the ground, a huge black tower towered into the sky. At its peak, four curved towers protruded towards the portal as if grabbing it. The tower was built for aesthetic reasons. In the end it looks similar to Sauron's eye tower from the Lord of the Rings.

Satisfied with his work, Tomoka decides to return to the real world. Slowly he opened his eyes once more just in time to see a pair of black balls staring at him from the bedroom door. In an instant that lasted forever, the expression of the girl at the door changed. Surprise, relief, worry, anger, many emotions displayed one after another and vice versa. 

“TOMOKA!” Unable to hold back her emotions anymore, Nozomi launches herself towards her best friend. The poor girl had been very worried for the past twenty-four hours. It has been an emotional rollercoaster for him. 

Tomoka on the other hand felt a little conflicted. Seeing Nozomi worrying about her was heartwarming, but at the same time it made her feel guilty. Not knowing what to say, she decided to remain silent while hugging her best friend. 

For a moment sobs quietly rang out in the room as Nozomi released all the pressure the situation put on her. Tomoka herself was gently combing Nozomi's hair. After a while more, the crying girl finally calmed down. 

When they separated Tomoka could now see Nozomi's face again. His eyes were red and swollen from crying. His brows furrowed into a frown while his cheeks bulged into a frown. It is more than obvious that Nozomi is angry. 

“Stupid tomoka! You idiot! you moron! stupid!!” Now that her worries and fears are gone, this is the time for Nozomi's anger. He smashed his little fist over Tomoka's head. Even though he was angry, he still measured his attacks so as not to hurt his friend. 

"Please promise me you won't do anything like this again or I won't stop!" 

"I promise!" As soon as he said that Tomoka was hugged again. A soft laugh came out from her lips as she returned the embrace. 

“You should also promise to always be with me forever” Those words came out of Nozomi's lips just as a mutter. However, because their closeness is enough.

"Yes, I promise" Her words were a bit strange but Tomoka did not mind it. Nozomi is just a four-year-old boy, who knows what's on his mind right now. 

“Forever” Nozomi's hug tightens up as if Tomoka would disappear if she let go.

"Nn, forever" At this point Tomoka did not pay much attention. He only agreed to have Nozomi calm down. 

“That promise, If you deny it I will hate you forever” Let go Nozomi said those words in a serious tone. 

Before Tomoka could answer his attention was brought to the open door to his room. Standing there were his parents and the ones he considered to be the doctors assigned to him. At that moment he realized that he had messed up. Nozomi is one thing but calming her parents is another matter. 

[Hopefully survive this one.you will need it] Kurama said in a carefree voice hiding laughter. 

'Yes, I'll need it'
