- Description from Novelupdates

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!

This is a world where humans, demons and mysterious beasts coexist. Humans cultivate mysterious qi. Demons cultivate corporeal bodies. Mysterious beasts cultivate soul perception. A legend says that in the middle of an endless rainforest, there are extremely powerful existences; they are called demon kings. Some demon kings have a tyrannical corporeal body, some are experts in illusions. Some demon kings are proficient in magic, some can even move mountains. Some demon kings are able to sense things thousands of miles away. These demon kings rarely appear in the human world. Even if they emerge in the human world, they would reincarnate in human form; assimilating with mankind while seeking to breakthrough realms…….

I am a holy knight. To be precise, I am the Church of the God of Light’s Sun Knight…in training.

The Church of the God of Light worships and serves the God of Light, and theirs is one of the three largest religions on this continent.

As the whole continent knows, the Church of the God of Light has the Twelve Holy Knights, and each one has his own unique personality and features.

To be the Sun Knight is to have shining golden hair, sky blue eyes, a compassionate nature, and a brilliant smile.

…even the Sun Knight-in-training is no exception.

The 38th generation of the Twelve Holy Knights have completed their term of office, yet the time for the 39th generation to take over is still far in the indefinite future.

The Judgment Knight is brash and easily angered; the Storm Knight and the Leaf Knight are always fighting nonstop, day and night.

Since childhood, the Sun Knight-in-training has watched the others grow from kids into adolescents.

What must he do in order to become comrades, who will fight through thick and thin for each other, with this group of “younger brothers”?

“Benevolent God of Light, may I ask when I will complete my training that has taken more than ten years?”
