"Every step Touya took down that ladder was accompanied by the sound of groaning wires. Given the board and other equipment strapped to his back, Touya was probably putting three times his average load on [the] rope."
Less certain, but I think that it's the same here:
“...If you’re saying that, then I sure hope that [the] body doesn’t explode into a fountain of blood,” said Touya.

“I thought the things in here tasted awful next to what we could find outside, but I was actually wrong! It’s quite good!” Metea exclaimed.
With it being Metea, might match her speech patterns, but as a normal sentence think 'tasted' -> 'would taste' might fit better

“I see I’ve lost,” Earl Schonheir replied. “You performed admirably"
Schonheir -> Schonheit

e.g., It's been a hot minute since I've seen you guys.

A faint,orange light glimmered behind the torii. The lively clamor of a crowd of people could be heard from beyond, inviting him to join them.

=> faint, orange (missing space)

V4P5, 8%: “Also, there are some pretty healers hiding out in the institute." - while possibly also true, there’s a word missing like “good”.

v3p2:

98% - I’d figure -> Not “I figured” (you’d have that problem)? When the previous line is: “All of my subordinates are older than me, so I was having trouble knowing how to handle them.”

V7p6 ~19%

[...] who'd only just declared himself was too old [...]

Should be either "who'd just declared himself to be too old" or "who'd just declared that he was too old".

V5P9, 41%: “How razor-thin wires sharp enough to cut anything they touched could parry bare flesh without slicing clean through them was anyone's guess” - one or other of these is incorrect because flesh is not plural.

46% (same para as above post): “It was plain to see Leah LP hadn’t dropped at all” - Leah’s

66%: “Now that they thought about it, they'd completely neglected to tell Blanc the whole thing about how inventories worked for NPCs, did they?” hadn’t they?

"As the on-site envoy of House Kaddour, Sylan spent time lending an ear to the questions and concerns of the evacuees—his subjects."
Sylan -> Sylvan

"After taking role—all accounted for—Escoffier addressed the group."
I'm not sure in the singular, as here, but presuming roll-call as the base word: role -> roll

v13p9:

71% - As for the person next to who muttered that overly dramatic comment, […] -> Missing word: Perhaps “As for the person next to her who muttered […]”

"Don’t tell me...her vessel rupture?!"
This one may be correct as is. As a normal sentence, rupture -> ruptured. If referring to her ongoing 'vessel rupture', probably correct as is.

"Ren panted for breadth, his hands trembling from exhaustion."
Breadth -> breath

"All the plots that had been playing out on the palms of his hands had turned to mist and slipped through his fingers."
I could be wrong on this, but I believe that the phrase is always singular (in the palm of his hand).

V18p5, 94%: "Maltose contains an enzyme called amylase..."
I'm not sure if this is the author being incorrect or if it was an error in translation. Maltose does not contain amylase. Introducing amylase (found in malt which could be made from barley) to cooked barley, potatoes, and certain other starches will begin an enzymatic reaction that results in maltose. (I'm not a chemist, just a nerd, so take the science explanation with a grain of salt.) I only bring this up because I thought there might be a chance the original Japanese text was misinterpreted -- even if my money is on the author just sciencing wrong.

v5p4 25% By defeating the Infernal Demonic Beast Haagenti, the empire had at least gained access to a painful plain that it could now develop. -> plentiful?

Should be knew.

~86%

Two pairs of eyes turned toward Ryo.
Both belonged to a white-haired man [...], and another man

"Both" should probably be "They" here.

v3p11 ~19%

" I apologize [...]

There's an extra space after the ".

~22%

[...] bright red once more.I couldn't [...]

~31%

[...] I smiled at him."Thank you [...]

Both missing a space after the period.

~34%

[...] learn how to smile, Much to [...]

The comma should probably have been a period.

~44%

[...] and resuming working.

Should probably have been "and resumed working". That being said, technically "being reminded about [...] resuming working" could work, but it's not nice to read. I guess "and resuming work" would be an alternative.

~47%

[...] way closer to us "Please, raise [...]

Looks like it's missing a period after the us.

~59%

[...] she said softly. I fear for the future.

Is missing the opening " before "I fear [...].

~78%

"'Just because,' you say?

Is missing the closing ".

~81%

[...] startled my father. [...] made my father become tense.

Maybe replace the second "my father" with "him"?

~84%

Naturally, Mer happily got on his back and had become very hyper.

The times of "got" and "had become", connected with just an "and", feels off.

"Reina was dextrous, so she could do anything, but she had said that Zelos was bad at it."
Seems both dextrous and dexterous are valid spellings, but with the latter being more common thought I'd make a note just in case.

While I'm noting things:
45% “This island is relatively untouched by human hands, and yet there are surprisingly many artificial things here.”
Seems a little definitive for someone with amnesia. Perhaps is -> seems (unless this happens to be a slip/foreshadowing and she knows more than she's letting on, or her subconscious coming through)

"The three of them had apparently gotten stronger lately and could beat some monsters now, but when their enemies got to the rank of rabbits, they still struggled unless they were ready to sacrifice themselves to take down their foes."
This could well be me being dense, or just simply forgetting previous events, but what on earth is 'the rank of rabbits'?

"As commander, I could easily order Pickle or even Jaffar to martial the concerned knights in my steed"
Steed -> stead
