Huh... Okay, I gotta admit, didn't expect that.

While Reading this Chapter I gotta say, I was thinking actually, first: WTF it's That Aruto?! Two: WTF, It's that Aruto and Izu?! Three: WTF, does this means HumaGears Exist but how exactly like in time basis Three: Bryce have told them about Oma Zi-O... Then I got my answer Four: Now, I'm wondering when they will found out and from who, will Bryce told them, or will it be Geiz all Dramatically, or will it be Woz who enjoy talking about Oma Zi-O like hell. Or Sougo who we don't actually get what's his deal... Well I was thinking all that and the fact that I should stop trying to guess the Another Rider just based in a mention or his appearance

reiwa rider! and a other geiz!, i my is son of some rwby girl?

I'd really like to see you use the dialogue I left in my Chapter 2 chapter review now that Geiz is here.

Well then...
VOLUME ONE: COMPLETE!

Riders met(To my knowledge): W, Fourze, Drive, Ex-Aid, Build, Zero-One.
Rider Powers Obtained: Fourze, Build.

Feel free to correct me if I missed anything, and I'm hoping for more time-hopping, Grimm-slaying fun soon!

Ooooooh god. Did Oma Zi-O kill Tsukuyomi?!

So, someone disappeared and Bryce is looking for Shotaro's help... I'm now going to say that I expect this to be a Another W episode but who knows it could be anything so... Cool Detective Style Writing when Shotaro's Narrating

huh. I wasn't expecting Jaune to be able to control Another Fourze's power as much as he did. Hell, considering he had to be forced into Another Form, it makes me think he could almost be a new fourze, even though the Rules of Zi-O kinda make that redundant. But still, A for Effort from Jaune! The idea of a sentient anotherwatch though... Is this foreshadowing Another Zi-O II perhaps?

You talk about trying to improve your work, but have you thought of getting a beta reader to help you instead of just saying you're trying in your author's note?

Oh good god. Jaune is the next Another Rider. Not only that, but there is a high chance that Geiz could show up out of nowhere in the middle of the fight and try to kill Bryce. Either way, something bad is going to happen next chapter.

Oh fuck. That's not good regardless of what Another Rider he is.

Good Chapter, if I had to guess which another rider I would say Fourze, since I feel like it the perfect person to talk Jaune out of his rut

Huh. I uh. I wasn't expecting this. But I'm happy! Can't wait to see who Jaune becomes!

Did. You. Just. Made. Tendou. Fuc*ing. Souji. Pyrrha's Father?! when I read those words, I was like, who the hell said that, and then read that it was Pyrrha and... Mind Blown... Well I'm gonna pull up a leg or something and just say Jaune is Another Kabuto, because... Well, you know, Pyrrha, Jaune, Canon-OGKabuto-is-Pyrrha's-Father... So it's the most probable but we'll he can always just become other Another Rider... This will end wrong somehow I just know it, with Geiz basically just waiting for a chance to beat the shit out of Bryce (I spelled it right? I'm bad with names), Jaune probably beating Cardin because of corruption caused by the Another Watch Power... And, well, Bryce it's... There to beat/help Jaune with the Watch unless I'm proven wrong by Geiz.
Side Note: I actually like Zi-O too, I sadly haven't ended the show, if I recall correctly I was at Ginga's debut during Kiva's Arc when I had to left watching the show because of Internet problems, but the next chance I get i'm gonna watch the movie (Heisei Generation Forever) and then continue where I left... I, at least, am watching the perfect Zero One (Masterpiece)... Did you saw Zero Two? Because even if he isn't that much different from the normal Zero One... This new form is kinda growing in me. Well I have dragged this to much and said to much what will probably happen.

...Well Shit...Also Damn it Cardin! Lest Jaune will get revengeeven as a monster rider. God another riders are just wrong!
