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 spent the evening satisfying Yumiko. A beast woman's stamina was higher than a human's, so Erika wasn't able to keep up. They bathed, cleaned up, and got dressed before leaving the room. Erika was still embarrassed, but she seemed to be a little closer to Yumiko after the night, bringing her something to drink and a plate for breakfast.

Erika sat beside Ryuji with Yumiko opposite them as they drank milk. Yumiko giggled before grabbing her bacon sandwich, her eyes looking at Ryuji and Erika like enemies. She really liked the taste of bacon.

'I should try to remember this.' Ryuji watched Yumiko eating her bacon, not sparing Erika a single glance.

'Does it only feel strange for me, that I enjoyed last night with both these women?'
