I'm not going to lie, this left me a little discouraged with the story, giving another character the power to summon anyone from their own world seems quite risky, it also doesn't seem like something that can last long while maintaining coherence. Well, you are the author, good luck dealing with this.
I thought it was going to be a summoning story. Like summoning things not people. Even though summoning a person and giving that person the power to summoning others from his world is not that good. I was happy when you gave the mc steel and made him the new MAXSTEEL , which had a lot of potential but now.... I don't know. But, you are the author so you would know what is good for the story. So, it is a matter of seeing what you will do from now.
