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 verdant forest shimmered with the sunlight. It's light shining through the trees, dancing in the gentle breeze.

"Ryuji~ hurry up we need to get back before nightfall!" Liana's joyful voice echoed as she skipped ahead. Nothing like the brutal witch or princess she normally portrayed.

"What are you even going to this desolate forest for?" Ryuji responded.

Liana spun around and giggled before sticking out her tongue. "I'm going to practise my magic and overcome this curse!"

She had the strongest powers he'd seen from anyone at the same age, but her body could not handle the magic. Though Liana seemed fine, there might be a burden on her mind because her black lightning would kill anyone but Ryuji.

"Don't tire yourself out. If you fall and graze your knee, I won't help you but laugh," Ryuji warned her as they both walked deeper into the woods.
