I Became a Demon Professor at the Academy

Incredibly disappointed by how it is going and will drop it here, even though I saw it happening a mile away from the first chapter. Basically, if you've read these types of stories before and you feel like you already know how it will progress, I'm sorry to say but yes, it will go that direction. It is very similar to "I Became the Knight That the Princesses Are Obsessed With."

The protagonist is essentially a plot device for the author to slap "harem" onto the story and call it a day. While at first it seems like he has a definitive personality—crude and distant, yet secretly warm, evoking the Korean love of "gap moe"—he quickly loses that the moment any real plot development happens.

**Spoiler**
He sets out to work at the academy to cultivate the protagonist and their party to prevent the world's ruin. Yet, he quickly pivots to wanting to aid all the dropout students for... principles? Sure, that's totally fine. But when the author tries to represent the protagonist as a "realist" and then pivots to being a "visionary" in a paragraph, it feels genuinely awkward. I think the only reason it isn't as harsh as it could be is because the protagonist's personality is left so undefined that there is less cognitive dissonance when the protagonist does things that are strange.

The second, game-breaker scene is when he kisses the fiancée of his host body out of nowhere and it's implied that he loves her.... Really? He loves the woman he had no idea about what he did to her until a few hours prior? Maybe, just maybe, it's a misdirect. But as someone who dislikes misdirection, I have no interest in continuing further.

Bear in mind, the protagonist said the chapter before this arc came that he didn't care for her aside from doing the quest. The next chapter, he is already fawning over her and trying to take care of her in his "tsundere" way.

There are also inconsistencies throughout the work:

**Spoiler**
For example, it's stated and suggested throughout the story that he has spent a significant amount of time in this new life in the demon world. Yet, not once has he investigated the history of the body he now inhabits nor delved into his relationship with the host body's fiancée.

However, it was suggested when he was fighting two servants of said fiancée that he did not want to hurt her feelings by killing them both. That would imply a level of understanding of who she is, that is suddenly absent when the plot demands it to be so for the sake of there being a "shocking revelation" that the host had caused the fiancée's suffering.

I highly suspect that the protagonist will end up solving everything by himself. The female leads will be utterly useless aside from harem time. It diminishes the value of the whole story when the premise is that he HAS to cultivate the "fantasy world protagonist" to defeat the demons, when he already has the power to do it. There is no power scaling evident to the reader aside from the first chapter, which is just too ambiguous to serve as a genuine reflection of the power levels.
