So many people think that Chika will one day become a Black Trigger. I highly doubt that unless they can figure out how to reverse Black Triggers back into normal humans. So I was thinking if it had to be someone else why not Chika's brother. We don't know much about trion but if there is a familial aspect to it, then he could also be a trion monster. When Tamakoma 2nd finally makes it to the Neighborhood and reunites Chika's friends and brother, we might see a serious battle that can end in the creation of a black trigger for Chika or someone else to use. I definitely think we will see the creation of one or two before the end of the series. The neighborhood may be one of the better times to create one. Especially if it is against the 1 horned Aftokrator guy.
