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 Crimson Rooster was located twenty metres to the south of the tailors, with quite a rustic look. The facade of the building was clad with thick red-coloured timbers while a small stone pathway led up to the main doors, which were a large white painted sign with the name on it in the same crimson shade as the timbers.

However, it seemed quite popular, with the first floor completely packed, while the second floor seemed empty; the moment Ryuji and his party approached the door, a beautiful woman in a red rooster outfit, even a small feathered tail poking from her buttocks made it look amusing, greeted them.

"Welcome to the Crimson rooster!" She said cheerfully while adjusting her large breastplate. "I am Roostina; may I ask if you have booked a table or are members of the adventurer's guild?" She questioned with a smile, even when she eyed Yumiko's fluffy ears.
