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

After a wonderful evening of dancing and an enormous feast, Ryuji found himself staggering along the halls, a maid helping him towards his room. 

He placed his hand along the wall while trying to focus his mind. The thoughts of Yumiko and Erika in their outfits tonight drove him crazy with lust. Because he drank, the usual restraints on his demonic thoughts vanished.

"Please take me to the blonde girl's room instead." His words slurred and stuttered, but the maid thought nothing of it because of how close the trio were.

Erika and Yumiko retired to their rooms first because Alan wanted a quiet drink with Ryuji to speak about the plans for tomorrow onward.

Though Ryuji couldn't remember much of that right now, inside his mind was a fiery desire, and it all but controlled his actions as the maid guided him to her room.
