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 guided Ryuji through the mansion, helping him choose a nice black suit that looked both smart and sleek. Ryuji's simple choice of a white shirt with a black suit and red tie went better than he expected.

Alan told Ryuji to sit down in the lounge and relax as he walked back upstairs to find some shoes to wear. Not long after, he returned in a flashy suit with golden thread and various accessories and a long black tie.

"What do you think?" Alan said, spinning around and showing off his suit.

"Wow! You look like a show-off!" Ryuji said with a huge smile on his face.

"Aww, you're so cute," Alan said, placing his hand on his chin as he approached Ryuji and stroked his face. "It's such a shame I can't have you wear the same flashy suit, though I must admit, you still look great in that. My little niece should find you quite appealing."

"Ah, isn't it amusing? Few know, but my big brother is actually the king! Haha."
