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 carriage rolled across the ground, creating a bumpy ride. Yumiko's tail lay across Ryuji's lap as if to keep him warm.

With Alan's departure, to meet the local lord, a heavy silence settled over the carriage.

His absence was palpable, his usual jokes and antics replaced by a heavy air of seriousness that seemed to weigh down on everyone.

'The clown should be here—otherwise, I might die of stress.'

Ryuji started feeling attached to Alan, maybe because of his past mistakes or because of how easily he got along with him.

He was curious to know why Alan hadn't entered the dungeon. Ryuji wanted to pry further, but he could wait until Alan told him.

"Ryuji and Erika, you two must be careful. It states that sometimes the fire type will cling to their enemy moments before death to ensure their explosion deals the most damage."
