Emote abuse/glitches.
It's not exactly speedrun-specific stuff, but as a gamer it's something I recognize. The RPG experience isn't complete without emote spamming. Do people really play RPGs without spamming jump at least once (at least for those games that have it)?
With all the lighthearted comedy I didn't expect a bit of heavier emotional stuff with the two girls' backstory. Damn, Eida endured repeated physical abuse as a child in the name of brutal "training". I was not ready to see that in a funny manga like this.
only the strongest swordsman can wear it
It's fun to imagine that some dudes in the past might have worn this same armor without regard for looks. True minmaxers would use it if meant having the best stats possible. I actually appreciate that Kiira was appalled at the atrocious aesthetics the "armor" had. Her outfit prior to putting it on actually covered way more of her body.
Lol, the entire S-rank party sequence was just a red herring because he wasn't gonna hire them anyway...
