Mediocre at best. It could improved though. The author completely butched the origianl series's character. Let's look at one example I made: You know Tess's father? The king of the elf race? The first interaction he had with the Mc is a no-homo joke. Wtf? This guy is supposed to be same character I remembered? Arthur, the original main character is butched too. He can't even be called aurthur anymore with the way he speaks. The gammar is so-so. Not that good. Anyways, I'll come back to take a look at this novel once in a while. I'll tell you if it improve. And please don't be too discouraged by my comments, author.

He can use his student's curse techniques, but the proficiency is cap at how good his student is at using them. Let's say he got Mahito onboard, he can use idol transfiguration.

He's kinda a hypocrite, isn't he? Didn't he criticized Nobara for leaving without a word? He's doing the same thing to his friend, Usagi. Heck, this is arguably worst. By not telling them that he's alive, he's causing them a lot of suffering. Guilt that would haunt the two students in question for a long time.

Oh god no...please no...Don't mix bleach into jujutsu kaisen! I am begging you!

Kenjaku?

The contract is just fucking pitiful, he's seems so desperate for smex.

U could also put effort into improving yourself, like exercising, or studying.

He doesn't know the ending of Melina, does he?

It's Gamera!

Finger crossed it's Gamera

But acnologia is a... -You know what? Not gonna even question that anymore.

You have sussessfully capture Guy Crimson! Guy Crimson has been added to the pokedex!

Would Marie ever have her big bro sub plot resolved? Despite her terrible actions, Marie actually cared for her brother the most in the world. In the Marie x Leon side stories, it was even revealed that her strongest mental defense was infact her big brother. It would warm my cold dead heart if the mc told Marie about Leon's feeling about her, maybe a few final words too. It would also be incredibly tragic to know her brother is dead again.

It melts your C*@$ off, that's what it does.

Won't that lube be...Acidic? It's all fun and games till your lil bro start melting...

Is his head 3d or 2d like a painting?

Imagine what the sludge villain must have felt as a child. You were normal kid then...*baam*! You look like a city's sewer personified. All of your peers stop playing with you cause you were the sewer monster, the teacher probably don't want to come into contact with you. In real-life, getting bullied by your peers could for "looking funny" early on in life could cause kids to go psycho later on let alone someone with that guy's appearance.

But that's Vongola the first's name...

That's just playing dirty...atleast give the others a chance at getting the spray without getting arrested for it.

She has great potential as a mushroom farmer.
