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

Inside the carriage, the silence felt deafening.

For Ryuji, the journey was a delightful experience, his eyes leisurely taking in the surroundings while he basked in the princess's extravagance and her one-way windows.

"Hurry and release me, you perverted villain!" Liana's voice carried a sharp threat, while her low and raspy voice caused Ryuji to become more amused.

"That voice doesn't suit such a tiny woman."

He turned to face her and noticed his hand seemed to have slipped down to her chest at some point—the soft and addictive feeling made him feel that his execution or death might come soon, so why not enjoy them fully?

"Ah... stop, why are you touching me... wait, it's dangerous!?"

A black lightning burst from the princess's body, causing the entire carriage to flash with dark light.
