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

Alan, a man of swift action, didn't allow the disturbances to linger. 

With a deft snap of his fingertips, a group of knights materialised and swiftly escorted the heroes, their armour glinting in the dim light, behind Lord Qwass to another room.

"Alan! You cannot do this. If you treat my Chosen like a dog, then why does yours still stand there!"

"Lord Qwass, your Chosen, made a direct threat. That is why he and his entourage were escorted to the room beside us. This doesn't mean you will be penalised or have any punishments because of their improper conduct." Alan's voice echoed through the room.

He reminded Ryuji of the king with how he controlled his accent and tone to gain the support of the upper visitors.

And he said he couldn't take the throne... What a damn fool

"It's Duke Grigor to you! Lord Qwass have some manners as a high noble. We are in the presence of others."
