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

Meanwhile, back at the fancy mansion near the castle. Alan sat across from a beautiful woman who made his skin crawl.

"Who is dear to you, old man? You only feel your mother and sister to be dear!" Liana responded while eating a cute rabbit-shaped cookie.

'Heh, you act like a witch, but in reality, you're a soft little girl! Ryuji, please come home soon!'

The crimson beauty took the head seat and sat with an air of authority. In stark contrast, relegated to the guest seat, Alan looked bitter while his fear was palpable as he gazed out the window.

Kathryn stood in her full armour, a silent sentinel behind the princess, her eyes scanning the surroundings.

Alan returned the other knights to their dormitories and then came to his home to relax.
