Unless it's a massive forest fire, the 'kingdom' is not on fire. The capital city, however, is.

A unicorn with wings, a cross between a pegasus and unicorn, is called an alicorn. Which is a word derived from the Italian word alicorno.

"This is just like a densely hoard of monsters!" Frickin' go back to school, and learn how to properly write sentences. It should be "This is just like a dense hoard of monsters!", or "This is just like a densely packed hoard of monsters!" And I wonder if the author knows that fungi don't have flowers or leaves. The fire 'fungus' looks an awful lot a plant to me, and there is a big difference.

Go back to school and learn the difference between there, their and they're. And a door doesn't creek, because a creek is 'a stream, brook, or minor tributary of a river.' A door creaks; (of an object or structure, typically a wooden one) make a harsh, high-pitched sound when being moved or when pressure or weight is applied.

'It contains electricity, but it's not dangerous.' Um, what? Just when was he born in 'our world'?

How does it jump from 5 hundred thousand in the last chapter to 5 million in this?

"There's a reason why you tell others important things." Short for there is. NOT "Theirs a reason why you tell others important things." Used to refer to a thing or things belonging to or associated with two or more people or things previously mentioned. Learn the difference.

One has to wonder why they can't re-use the 'failures'? Melt it back down and try again.

Anyone wanna bet he kisses her to break through?

So, nobody else is thinking that Ruka is going to end up transforming due to her continuing thoughts of being 'weak'?

"My magic can't move because it's hitting something at your right hand." *face palms again* At YOUR right hand? It's Cain's hand. "My magic can't move because it's hitting something at my right hand." This isn't the first time these scanlators have done this, when Cain is thinking to himself and he says 'your' instead of me/my/myself.

The proofreader/QC needs to go back to school. Their father says "I'd like it if Cain could acquire magical manipulation by the time Benjamin is staying." Benjamin just got there. *face palms* It should say "I'd like it if Cain could acquire magical manipulation by the time Benjamin is leaving." And if the mangaka had it that way, they need to go back to school, too.

Uuuhh, how is 'Unlimited Magical Power' a weak skill? And if you know what you're doing, 'Magical Array' is no slouch either.

Dude's too young to have learned that t*ts are t*ts. Small are just as good as big, as long as they're NICE. Flat bewbs (pancake), saggy bewbs, just plain ugly bewbs, those are the ones to avoid. Mio's really weren't that small, and they were well formed. I wouldn't say no to getting my hands on hers.

Liquor or liqueur, not liquer.

Liquor - an alcoholic drink produced by the distillation of grains, fruits, vegetables, or sugar that have already gone through alcoholic fermentation.
Liqueur - an alcoholic drink composed of spirits (often rectified spirit) and additional flavorings such as sugar, fruits, herbs, and spices. Liqueurs generally contain a lower alcohol content.

Yes, Moyu's older sister is a beauty, but Yiyi's not a hag.

Okay, why does a character who has never been to our dimension/world know French?

It wouldn't be sharpening his weapon in blood, it would be quenching it. You can't sharpen something by immersing it in liquid.
