After saving a girl and then getting run over by a car in the process, and "I" was reincarnated as"Rex" in a video game world. A handsome Rex with skills in all fields, but he is a helper character in the early stages. Tho Rex has a high level, balanced skill set and multitude of abilities…He's useless in the later stages of the game!!

I decided in the face the fact that I'm useless in this fantasy world

So let's relax by letting the main character of the game do both "saving the world" and fighting for his life against monsters"!　

This is a story in which an ordinary person looking for a "hero" but instead becomes a hero who saves the world for some reason!

In the year 20XX.

Despite the fact that the citizens are monitored by IC chips, making the identification and arrest of criminals easier, gruesome murder cases targeting children by an unidentified serial killer are occurring all over the country.

Clad in a black cloak and a clown mask, a deranged serial killer known as the 'Murderous Clown' who poses 'questions' to his victims — the battle between him and the police officer, Yuuto Asakura, begins!

I reincarnated in a novel inside the body of a villainess named Eris who poisoned herself when her fiance, the prince, married her childhood friend, the maid Helena.

From the moment I realized this, I had only one goal.

Escape from the world in this novel.

Even after being dead, I tried to get out of this world but the 'world' did not allow it.

However, when she rejected the path of "Eris" in the original novel the men who had persecuted and ignored Eris began begging for her interest and affection.

“Who are you?” the priest who revived Helena asked.

“You... Are you really Eris?" even the warrior who pledged eternal loyalty to Helena also asked.

“You have changed.” said the prince who rejected Eris in order to marry Helena.

It was strange.

Everyone wasn't interested in Eris before. I don't want to get affectionate even after time passes.

She has no confidence in loving this world.

On her 12th birthday, Angele is infected with the strange and fatal disease that causes feathers to sprout from the body. She is sent to a solitary institution to be quarantined where she meets a man named Hakana and the wheels of fate begin to turn. (Source: Mangaupdates)

From DrCoke at MangaHelpers:
He has never been the type to stand out in the class. Kurihara Yuzuru has lived life by avoiding entering the lives of others, staying to himself. The story begins where he has to go to a whole new school, which means new classmates. He lacks any confidence to make new friends, so the fear of rejection drives him into a wish he never thought he would make. This single wish leads to a first day of class he would never forget. Yuzuru will have to make choices that will significantly alter others' lives, choices he could never make in the past.

The brave tale of the peerless Great Emperor Leonard the First was evaluated as a universal truth.
However, in his younger days, before he managed to unify the continent, he was a boorish and clumsy young man, he got his homeland taken away from him and was branded with the infamous name of “Nosferatu”. This is the story of a great counterattack, a great revolt.

Several great generals, sages, talented women and geniuses comparable to gods and demons got attracted to the single-minded Leonard and congregated around him. Eventually, they became a great force able to engulf their depraved fatherland and contended against rival countries.
