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

The moment that Alan brought Ryuji into another room, he slammed the door. Yumiko and Erika were waiting with the princess because Alan asked for some time with Ryuji. Alan then immediately dropped to his knees and placed both palms on the ground.

"Forgive me, Ryuji. Though I believe you understand my meaning. I still used you as a betting chip." Alan's voice, thick with remorse, sounded hoarse and gritty as he slammed his forehead against the floor.

Though it felt dramatic to Ryuji. Alan, who made many promises. Might have thought that Ryuji felt betrayed.

This guy is really too serious for his good...

Isn't he doing me a favour? Despite this, he's almost crying.

"Alan, stop being dramatic... I don't think you were wrong, and this isn't going to be so simple, right? You are her uncle and likely have already discussed something of this nature in the past."
