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

Ryuji felt comfortable—a warmth enveloped his lower body, creating a slimy sound as something sucked on him. He felt exhausted from the constant battle and fell asleep the moment they returned; now, a soft pair of lips touched his cheek, and the warm, sticky sensation around his lower body moved faster.

Ryuji's mind remained dazed before he opened his eyes. His hands caressed a soft cheek and long blonde hair before he kissed her. Her soft lips pressed against his, and his tongue invaded her mouth, a strange taste, not the usual but still delicious. A pair of hands pushed against his chest as if to resist for a moment before slowly slipping around his neck, her tongue moving more aggressively.

'Her kiss feels rather awkward, like when we first started... is Yumiko nervous?'

"Yumiko..." Ryuji grabbed her hips and pulled her on top of him before grasping her ass and slipping his hands inside her pants. "Eh?"
