Reviews about Tensei Shichatta yo (Iya, Gomen) manga

Review 1

It isn’t horrible, but it is cliched and monotonous. The main character gets reborn into an universe where the whole magic mechanism is Japanese, but everyone there has a hard time pronouncing Japanese, thus his only real advantage is that he speaks his own language and has an absurd amount of mana.


He acts like an OP kid while being brilliant, and it all goes his way. attends magic school, destroys the magic reading equipment, and is basically OP. There are plot attempts, but they are all just variations on “mystery figure wants him dead, but all their machinations are easily thwarted because he’s OP.” That’s there.

It’s not bad; it’s just a little monotonous.

Review 2

Some stupid MC, who is being educated, decides he wants to be ugly rather than his highly attractive and popular self and inadvertently kills himself with a vase. (Really, the death was so absurd and unfunny, a truck would have been preferable.)

After expressing his desire for a normal life to the god, the main character (MC) is resurrected as a super OP with attractive appearance. How so OP He will be the greatest at magic because the narrative is so poor and the new world’s language is Japanese, which only he understands. What’s worse is that there is no creativity in the world-building; it is essentially a Japanese system with Japanese appearances and attire.

To live a normal life, although the protagonist goes to great lengths to master magic and then hides it half-heartedly. By chapter 20, however, everything is revealed, and the plot’s premise and aim are destroyed. Enemy? What terrible writing—some wicked organization is seeking to kill the MC for little or no apparent reason, and just the MC.

Chapter 1 starts out strong, but it rapidly deteriorates and diverges from the plot. As of chapter 20, the new planet has no substance or character development.

Characters are simple, elderly Japanese individuals dressed in traditional Japanese garb. Nothing fresh, no character development, etc.

Review 3

Although I assumed I wouldn’t enjoy this manga after reading the description, I was surprised. Although the manga is full of clichés, it does employ them in a way that is rather original.


The main redeeming feature is that this narrative isn’t about the OP young lord being OP (though he is), but rather about him attempting to blend into the new society.

A pleasant read if you want to kill some time, but there’s nothing revolutionary.

Review 4

In essence. While sometimes being harassed by others, MC is OP and attempting to hide his potential.

Very formal and petty. It’s remarkable how many conversations you can skip and yet comprehend the main idea. The friend of the MC, who is cliche from bottom to top and acts as an introduction, is the saddest thing (I wish he would appear less often).

I apologise for not being objective, but I prefer natural flow, and in this instance the narrative sticks too closely to the plot. It appears forced and fake.

Clean and simple to read, Art and Style.

Shirokuro Sansui, a Japanese student, was sent to a separate universe after dying due to God’s error. He stated his desire to become “the strongest,” for which reason he was given 500 years of instruction by the sage and a recommendation letter from God delivered to a sage.

He stumbles upon a newborn close to his training grounds after he has achieved the point where he may be considered “the strongest” by the standards of the regular people, and from there he begins his adventure in another realm.


He is the strongest but appears to be simple; his skills and training were straightforward. The fight of the unassuming Sword Saint has just started, with a basic wooden sword in hand.
