There are 3 digits in the post title because I’m hoping UQ Holder will break at least 100 chapters.
Although there’s only one character physically introduced in this chapter, there’s one explicitly drawn and another referred to in an offhand comment. Yuuki Shinobu, although probably a girl, her gender is not explicitly mentioned. Up for a trick somewhere down the road? I hope it’s a guy, just because.
Translation side note. Translation is hard, let me start with that. “Sir” is about as close to “senpai” as you can get in this context. “Boss” is the usual translation for “aniki”. “Onii-chan” is a tougher case. I can’t think of a suitable English idiom in this context (“big boss bro” is definitely not it, but what is?). Then again, I would be lazy and just keep it as onii-chan. This is just a small subtle difference to keep in mind. I don’t really want to turn this into a translation discussion. The real reason though I bring this up is that I just want to get that onii-chan loving going on (♥Dave). End translation side note.
The other character, some guy Shinobu knows, actually has a character design, so we’ll probably see him back in one form or another. The last character is one of Touta’s friends and apparently a genius mechanic. I think he might be referring to either one of the four friends you always see together or the android/power suit guy we saw in the first chapter’s splash page.
There’s some stuff about dreams, dreams that are completely unrelated to battle of any kind, Touta even outright denying the need to become stronger. We’ll see where this series is going.
