The Second Shield Hero

Lieutenant Adamescu is a police officer at the Republic of Vardarska who has been serving in the Special Mobile Police, the country's SWAT team. He is famous among his colleagues for using his infamous 'Shield Attack' method in anti-terrorist operations by charging at the threat with his ballistic shield, which has earned him the nickname 'Bumper'.

One day, after an anti-terrorist drill, Adamescu is on his way back to the station when he comes across what appears to be a book originating from the late middle ages. After reading the first page, a white light manifests around him and he vanishes into thin air only to reappear in the middle of an old castle.

He's not the only one though. Along with him, four other individuals, of Japanese descent, have also been transported with him in order to become what is known as the legendary Cardinal Heroes with his presence causing confusion as to who is the real Shield Hero.

After Naofumi, the other Shield Hero, is accused of a crime he didn't commit, the Lieutenant decides to side with him and helps him escape from the castle.

Now stuck in this world and with no way of returning, Naofumi and Adamescu embark on a journey to fight the unknown threat known as the Waves while also trying to prove the former's innocence, meeting Rapthalia, who joins them in their journey.

This fanfic will not follow the anime's storyline. After the anime's downfall and decrease of popularity, I have decided to write my own storyline to give it some justice. I'm open to criticism.
