She is not smart. She thinks she is brilliant, but every "plan" she makes accidentally saves the kingdom. The narrative describes her as a "gaki" (brat) trying to survive using her diary from the future. Hilarious and heartwarming. 7. The Dark Horse: FFF-Class Trashero Author: Farnar

This is the quintessential "Gaki ni Modotte" strategy series. Desir looks like a weak student but commands the respect of adults because he has already fought a war. The "Best" part is watching him speed-run his education and recruit powerful allies before the tragedy strikes. 3. The Psychological Nightmare: Redo of Healer Author: Rui Tsukiyo

Technically the granddaddy of the modern trend. Satoru Fujinuma has a "Revival" ability that sends him back 18 years to prevent his mother's murder. He is a 29-year-old man trapped in a 5th grader's body.

Cid Kagenou wanted to be a "mastermind in the shadows" in his past life. After dying stupidly, he is reborn in a magical world and immediately begins pretending to be a weak noble brat.

The "Gaki" trope isn't just for boys. Princess Mia is executed by guillotine, wakes up as a spoiled 12-year-old brat, and frantically tries to avoid the guillotine again.

The protagonist has lost his mind. He treats everyone like NPCs. His "Best" strategy is to speed-run the story by killing his allies to save time. It satirizes the entire "Yarinaoshi" genre. 8. The Realistic Grind: Again!! Author: Mitsurou Kubo

These aren't your typical "I fell into a river and saved a cat-girl" stories. No. These protagonists are usually betrayed, bankrupted, or murdered in their original timeline. They wake up as children (the "Gaki"), retaining the memories of their miserable adult lives. Their goal? To use their future knowledge to crush their enemies before those enemies even know they have one.

This is the . A 55-year-old business magnate is killed by a rival, only to wake up as a 10-year-old boy in his old house. Instead of swords and magic, he uses stock market predictions and real estate knowledge.
