TheDragonSlayer

“Ah... foolish hero, come to slay me... Heed my command and kneel!”

The Demon Queen offered Ryuji half the world—however, he desired everything.  
-------------
Ryuji Vincenzo, a misunderstood son of a female gangster, beats his teacher upon seeing him commit a crime against his friend’s girlfriend. Yet because of his looks, the school forces him to change schools instead of expelling him. 

However, on his first day of changing schools, his class gets summoned to another world. 

He gains a useful class, but the calamity star chooses him. The star signals future tragedy or conflict in the new world. Despite this, the king, although asking them to fight against the demon king, doesn’t threaten them and is quite likeable.

Thankfully, the students are all given the power to fight, and this new life looks up for Ryuji, who desires to make friends and find himself a girlfriend.

Ryuji himself is quite a handsome man because of his father, but his mother's strict rules make him a strange person who wants to connect with people. 

This leads him to help those who cannot fight who would die otherwise. He wields a massive axe and uses his talents to support the weak members of his class.

This novel is a repost, as I became ill when writing the previous version and fell behind too much.

Extra Harem: S-Rank Berserker in Another World

After three hours of practice, Alan called for the ladies to take a break and freshen up. In the afternoon, they would visit the castle because the king called a meeting, wanting to see all the heroes.

Ryuji felt a surge of genuine joy at the prospect of seeing Akari and Ryo again, though he knew that things might have changed. He was determined not to let this alter their relationship.

'Even if they said those things because of the trap's gas. I won't leave them to rot alone in that place... Now that I know Heroes is a commodity to the kingdom.'

He wasn't a superhero, but those two were nice enough to him, and he thought having a tailor and chef might help in the long run.

"Alan, can you tell me how bad the heroes are really doing?"

In the private room of Alan, Ryuji sat on the sofa opposite him, the creak of the wood resounding as he took a glass from the table and motioned for Alan to fill his cup.
