An incredibly athletic older brother, Tenryu Taiga. A programming genius girl, Tenryu Fuyuki. The two siblings separated for eight years ended up living under one roof again after facing the problem – a lack of funds for living expenses.

Fuyuki proposes a way to earn money, a core system deeply involved in people’s daily lives, a game that awards you money as a prize for defeating malicious bugs in cyber world, the 《Aries》structure. Taiga after becoming a warrior in the game relying on his inborn senses, is puzzled by the unfamiliar sensation.

One day Saionji Rui, Fuyuki’s best friend appears and is attacked by a mysterious bug― “I’ll be waiting, my prince.”. Hybrid fantasy battle of cheating siblings begins here!

A dungeon core novel. But with bees. A bee dungeon, if you will. Oh, and something about a young man finding his place in the world and maybe learning about the deadly calamity that threatens all of humanity. But mostly the bee thing.

”What is justice? What is evil? If given a second chance, I would no longer care about the opinions of others and only seek immortality.“With a cry to the heavens, Dusk Vale met his tragic end.But fate had other plans. He was granted a mysterious power that sent him back 300 years to the moment everything began.In this new life, he would live without concern for the judgments of others. No more restraint, no more hesitation — he would use any means necessary to achieve true immortality.What is the best villain? In my opinion, it is someone who does a lot of evil but is still considered a good person by some people. Someone who never really thinks about others but has many people who are loyal to him.Can one person defeat the entire world? Stupid, humans are born on the same level; surpassing one person is already not easy, let alone surpassing all of them combined. That is why Dusk will absolutely not act alone in this life.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?
