Third person POV
School time is over and as he was walking home with Hoshi and his friends, Taro revealed to them that Sha is a Negative Energy master.
"What?" Bokuto commented in shock.
"Really?" Hoshi added.
"Woah…" Saki is not shocked at all, and she was amazed by it instead.
"Yes, he is," Taro replied, "and he can help us train in that."
Kuro, as usual being within Hoshi, was skeptical but intrigued by it.
"Woah, sure," Hoshi responded with accepting it.
"Hmm, it will give us advantage against yokai, too." Bokuto folded his arms.
In time, Sha came to them. "Are you ready for your Negative Energy training?" They looked at him.
"Yes," Taro responded enthusiastically.
"Okay then," Hoshi added.
"We're ready for anything, sensei," Saki added as well.
And so, Sha took them to an abandoned warehouse in the outskirts of the city to begin their training. There he told them, "Alright, listen up, energy is a byproduct of your emotions. Depending on your state of emotions, it will affect the energy you're channeling." His students then understood and get it.
"Good. Shall we begin our training?"
Sha asked that with a cool determination on his face.
They said yes. And so, their training had begun. They were trained to focus their emotions and channel the negative ones as energy on their hands. All of them did so since they have some negative thoughts that translates into emotions and thus, into energy. Some of those thoughts are not even related to their personal problems. Sha observes them while nodding approvingly. "Good, keep on going. We still have time before sundown."
They continued on training. Their first lessons are on focusing on their emotions and channeling them into energy.
Later, at 5:55 p.m., they all left the warehouse and went back home. Along the way, Sha parted ways with them and went to his master's home a few blocks away.
"Bye!" Hoshi said to him.
"Thanks for everything!" Saki added.
"See you tomorrow, sensei!" Taro added as well.
After that, they continued walking home. Shortly thereafter, Taro parted ways with them, before boarding a city bus home. With that, Hoshi and his friends continue their way home.
Later in the privacy of the bathroom at home, Hoshi was talking to Kuro via a mirror.
"How was the training?" he asked Kuro happily.
"Well, it was quite unique for it," Kuro replied while thinking. "He's getting more trustworthy than I thought. But still, we must stay vigilant at all times."
"I know. We will watch out for him."
"Good. You may go now and do your thing."
Kuro then disappeared from the mirror.
With that Hoshi left the bathroom and went to his bedroom to rest up and do his favorite things and hobbies.
