Man, this chapter was a rollercoaster.
"Ren you demigod dumbfuck, create something to protect yourself!"
"Huh, well, okay, yeah!"
"What, no wtf??"
The most obvious shit to make would be an emergency bracelet that activates blink or a barrier, the moment magical energy is cut to it (i.e: when she's drugged), or a golem that can always escort her. I'd even consider to make an army of birds and rats, that always report to me and follows me around, if it's nit absurdly difficult to make AIs, essentially.
But anything BUT a bloody mecha.
P.S: Also, the most obvious call-to-adventure ever was ignored here: Find out how the bandits ambushed her?
You can't just go: "Kuku, you can't just rely on these skills, there's more to the world than that!!"
And then just....Ignore it?
I am getting a bit too amped at this shit, but that was a really weird arc here.
