What is the bright side?

The boundless shadow void.

Compared with the power of light that represents the order of the universe, the power of shadow that interacts with it will make people involuntarily have negative associations.

The Old Gods, the Lords of the Void, and… the unavoidable loss of control.

Is the power of shadow really difficult to break away from the control of the ancient gods and cannot be truly mastered by mortals?

The traverser Andrea has a different opinion on this.

Accidental crossing, came in Azeroth’s most dangerous period of the ancient war.

Andrea, who was blessed by the moon god Elune, had many questions about this world she thought she was very familiar with.

“Moon God” Elune, is it really just the Moon God?

Since she is not the Titan star soul that people imagined, what kind of existence is Elune?

Why did Tyrande gain the strange power of the so-called dark side of the moon when she sacrificed to Elune in the future?

If, I mean if.

Even after traveling through time, you still encountered your enemy.

That figure you can never forget in your life.

He has the ability, he has the cheat code, he has everything.

He is the so-called "protagonist".

And you're just a lowly "programmer".

I'm looking forward to it, I'm very curious.

[My next novel, "The Charismatic Man Has Friends Everywhere in Detective Conan," is now available. Click on my author page to follow my new story!] Synopsis: Ten years after transmigrating, Atobe Keigo discovers he has a younger brother named Keigo. He glances at news of Samurai Nanjiro's winning streak and the famous actress Yukiko's retirement to marry the renowned mystery novelist Kudo, then looks at his ten-year-younger brother Keigo, who's currently drinking milk and blowing bubbles, and sighs wistfully: "I don't want to be a criminal!" He's bound to a "Criminal Master System," which says that by appearing at various crime scenes, he can acquire various criminal skills and become the world's strongest criminal master. Those who frequently appear at crime scenes are either criminals or police officers. As the eldest son of the Atobe family, and with a younger brother named Keigo, why wouldn't he enjoy his comfortable life as a rich second-generation heir, instead of playing tennis, why would he choose to commit crimes? Especially crimes in this Detective Conan world! But the skills listed in the system were so tempting: Demolition Specialist, Medical Specialist, Disguise Specialist… So Atobe Keihara went and got into the police academy, setting a small goal: to become the Superintendent General after graduation! Then, looking at his curly-haired classmate Matsuda, who claimed he only became a policeman to beat up the Superintendent General, Atobe Keihara fell into deep thought: “…” Atobe Keihara would kick his classmate's lunchbox, prevent various murders, and thus acquire various criminal skills. Why could he instantly catch that thief? Because he acquired the 'Theft Specialist' skill. Why could he tell at a glance that the murderer had just killed someone? Because he acquired the 'Assassination Specialist' skill. Why could he easily defuse such a complex bomb? Because he acquired the 'Demolition Specialist' skill. … Criminal skills stronger than those of criminals appearing in a righteous police officer would only leave countless criminals weeping. Thus, a noble young detective who could see through people's hearts became the nemesis of criminals and the light of the Metropolitan Police Department! Reading Guide: ① This story is set in a fictional world, unrelated to reality. All background settings are fictional. There are many personal settings, and any discrepancies with the original work are based on the fictional settings in this story. [In this fictional setting, Japan only has a Metropolitan Police Department, not a National Police Agency. See Chapter 44 for details on these settings.] ② The protagonist is Keigo's older brother, but in this story, their hair colors are different. The protagonist has purple hair like Keigo in the anime, while Keigo has blonde hair as depicted in the manga. On the cover, the younger brother is a first-year middle school student, and the older brother is a police academy student. ③ The main focus is on Detective Conan. The tennis plot is minor. This story primarily tells the tale of Atobe's older brother becoming a detective, a satisfying and overpowered story for the protagonist! ④ The protagonist is purely on the red team, not an undercover agent. He is in the same cohort as the police academy group, so he will kill them off in a butterfly effect-like manner. This is not intentional rescue, as the protagonist is unaware of the police academy group's storyline. ⑤ The protagonist is backed by the Atobe Group, and his insightful observation skills, no less than his younger brother Keigo's, are maxed out in solving cases. He also has a system cheat code, with both his combat strength and intelligence at the top level, allowing him to rise through the ranks at lightning speed. ————↓↓↓Advertisement Time↓↓↓————【Completed Novel "Yukimura-nii-san is the World's Best"】In his previous life, Yukimura Haruki was a tennis prodigy just one step away from a professional Grand Slam. However, he died unexpectedly on the eve of the finals and was reborn into a fantasy tennis world. He discovered that his talent had become even stronger after his transmigration, especially since he also possessed a tennis training master system, essentially having the best coach to tailor-make training plans for him. Thus, Yukimura Haruki's goal was to reach the top of the world in this unscientific fantasy tennis world. Unexpectedly, in the year he was four years old and preparing to formally learn tennis, his mother became pregnant and gave birth to a younger brother, giving him a very familiar name. Shocked Yukimura Haruki: "..." He never expected his younger brother to be the son of Rikkai's legendary tennis star!!! But my soft and adorable little brother is so cute! Let's set a small goal: to become the older brother he admires most! ———————— [Pre-order novel: "The Charismatic Girl Has Friends Everywhere in Detective Conan"] Yuuki Tsukimiya loves making friends, and she has countless friends. No one would refuse to be her friend. From 99-year-old grandparents to toddlers, everyone is willing to be her friend. However, what troubles her is that there are always perverted criminals infiltrating her circle of friends and then murdering them. With love triangle murders happening around her every few days, Yuuki Tsukimiya can't stand having perverted admirers trying to kill her close friends out of jealousy. She decides to become a police officer, determined to arrest and imprison these perverts and protect her friends. However, she didn't expect that even as a police officer, she would still be surrounded by a battlefield. Even her friends at the police academy would be targeted and murdered because of her. When Yuuki Tsukimiya tries to distance herself from her friends to protect them, they say: "Idiot Yuuki, the criminals are wrong, not you! We're not going to be so cowardly as to be taken care of by criminals!" So, Yuuki, don't even think about leaving us! ——————————Mini Theater 1: Q: Let's interview everyone. What's your deepest impression of Yuuki? Kagemitsu: When she opened the closet door and told me everything was alright, she was a ray of light illuminating the darkness. Furuya: She dyed her hair the same color as mine and said we were the same. Matsuda: She said she was willing to believe me unconditionally. Hagiwara: She naturally assumed, 'If it's Kenji-chan, it'll definitely be fine,' what a sweet trouble. Gin: (Lights a cigarette and sneers) That naive woman, laughable kindness... Hmph! Akai: Miss Angel has a charm that makes people want to get close to her. <<<<<<Mini Theater 2: Rum: (Orders his confidant) Get rid of that troublesome Tsukimiya Yuuki! Confidant: (Stabs him in the back) I'm sorry, Lord Rum, Yuuki is my friend, I can't hurt her! Reading Guide: ① Let's start writing from her infancy and raise a cute little Yuuki together! ② Kicking the lunchboxes, starting with the lunchboxes of Morofushi's parents. Because the female protagonist is unaware of the plot, it's a butterfly effect-style kicking of lunchboxes, not a deliberate act of charity. ③ The female protagonist is a gentle, oblivious, and stunningly beautiful woman, extremely loyal, and very sincere to her friends, so she also receives genuine affection from them. ④ The female protagonist has high combat strength; she can break a telephone pole with one punch. Girls need to protect themselves! ⑤ The female protagonist is incredibly popular; her beauty is causally perfect, so she is loved at first sight, unforgettable, and wildly adored. It's normal for various characters to love her; even strangers, passing cats and dogs, love her. Love is different in nature and not limited to romantic love. I hope readers will also love Yuuki. ⑥ Because the female protagonist has lived surrounded by love since childhood, her life is filled with affection, so she is oblivious to love itself. Since everyone loves her, she thinks it's just normal social interaction, and everyone is just a good friend. ⑦ The romantic pairing is undecided; after all, there are too many men in Detective Conan, so it might have an open ending. The original official pairings will not be broken up. Those who are paired with the heroine will only have pure friendship and appreciation for her beauty, without any romantic feelings. ⑧ Although the heroine is incredibly popular, she doesn't possess the same "Tomie-like" beauty. She's so beautiful that no one can bear to hurt her, not even the villains. It's not an exaggeration for criminals to turn themselves in because they fall in love with her. ————↑↑↑End of Advertisement↑↑↑————Theme: Combating crime is everyone's responsibility!
