As a result, at the age of 15, he held the position of Brigadier General.Despite traversing battlefields worldwide, he finally managed to return to Japan. The joy of returning home was short-lived, as news of an underage boy in the military started to leak to the public. In response, the military high command ordered Yuusuke to attend a military school called the Special Operations Soul Armor Academy and undergo a revision of his military records.Yuusuke, secretly pleased at the prospect of reclaiming his youth, faced numerous troubles, whether due to the nature of the unique school or perhaps because he had been in constant battle since childhood.

Veyne came from the life of sewer rats.The world saw him as a failure. He called it belief. Others called it stupidity. Either way, it was the only thing he had left.Even at rock bottom, Veyne never stopped believing in himself.Betrayed by his lover and brother, treated as a burden, and forced to slave endlessly in the game to chase his dream—he endured it all.Though late, his obsession was finally rewarded with an opportunity. But the sewer rat in him was too weak to hold onto it. He had fought the world and lost.Actions have consequences. And when he failed in the game, those consequences caught up to him, leading to his death.But the universe wasn’t done with him yet.Given a second chance, he returned to a time when the game had already been out for two years. This time, he rushed to obtain the Template Wilder class—the very class that led to his downfall.One of the game’s rarest hidden classes, the Wilder class, allowed him to switch into different forms based on the monster templates he possessed. An overpowered ability—but it came with a fatal catch.A hidden template forced him into the form of an ancient baby creature, one so cursed that players, monsters, and even NPCs would hunt him down. If he died in that form, his character would be permanently deleted.In his past life, he underestimated the class’s dangers. And the world tore him apart for it.This time, it wouldn’t be just hollow belief.This time, he’s not here to survive—he’s here to dominate.No emotional ties.No second chances.The entire game is his enemy, and he will crush anyone who stands in his way.He failed once. He suffered. He died. He was erased.Not this time.This is the beginning of his legend. The era of Veyne Draven.

My mother is the sweet, silly, and innocent protagonist of an angsty novel.

My mother was the substitute for the overbearing CEO’s unrequited love interest who ran off when she found out she was pregnant.

As for me, I’m nothing special. I’m just the child prodigy who became a hacker at the age of five.

…

Genius hacker Gu Chu found herself reborn in the pages of a tear-jerker book.

She had been transformed into a cute little five year-old. Her mother was the tragic female protagonist while her father was the uncultured, boorish male protagonist. There were also a gaggle of hostile, opportunistic relatives and a pretentious, seemingly-virtuous but vile-hearted aunt...

Gu Chu straightened her small little frame and began waging war secretly to help her mother.

What bad intentions could a five-year-old have?

She just wanted to protect Mama.

…

Until one day...

The man who had hunted her across half the globe in her previous life suddenly appeared.

As he stared at the weeping little doll-like child in her princess dress, the man fell silent for a long while.
