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 morning arrived with the relentless force of a storm for Erika and the group. Not only was she deprived of sleep, but she also felt frustrated. She followed the group along the dirt path with unsteady legs. Her face and eyes were puffy from the late night.

She wanted to recover while enjoying the sweet scent of evergreen and coppery earth flowing into her nose with deep breaths as she tried to wake herself up.

'How did they manage to keep going all night and still look so fresh!?'

Erika clenched her teeth, watching Yumiko and Ryuji, wondering how they could spend the evening like that. Yet still so fine—though she noticed Yumiko's weak steps, Ryuji seemed perfectly fine after all that movement.

"He's like a beast in human skin..." Erika whispered while biting her lower lip, unable to deny the appeal of what she had experienced the night before. However, the feeling of lead and jelly from her legs made her equally fearful.
