There are several common tropes in anime that fans either love or hate. Some include the villain with the tragic backstory meant to humanize them and the hero with seemingly limitless power who, with each battle, breaks their proverbial glass ceiling to achieve greater power. Each of these tropes serve the characters and their story in unique and varying ways.
One such trope is when the character finds themselves in the right place at the right time. Without fail, major plot points can be launched or uncovered by these chance coincidences; they set the stage for their respective shows, getting the ball rolling for the plot, premise, or major conflicts their characters are forced to face and endure.
10 Emma & Norman Learned Gracefield's Secret At The Gate (The Promised Neverland)

What they discovered instead was a crucial, yet horrifying, secret: their home was a farm and Mom raised them to be eaten.

9 Tanjiro Avoided Slaughter By Sleeping In Town Instead Of Journeying Home (Demon Slayer)
The Demon Slayer world was relatively peaceful for Tanjiro Kamado; he worked as a charcoal seller to support his mother and five beloved siblings. After selling his stock and assisting villagers in a town nearby, Tanjiro was forced to sleep at a customer's house because the road home was too dangerous to traverse in the dark.
But darkness wasn't the only danger the Kamados faced; while Tanjiro slept, his entire family was slaughtered by a demon. He began his journey as a demon slayer to avenge his family, while also aiming to restore his demonized sister, Nezuko, back to life. Had he returned that night as originally intended, Tanjiro's would've been just another body for wild demons to feast on.
8 Light Found The Death Note While Daydreaming In Class (Death Note)
Before encountering the Death Note, Light Yagami was simply one of Japan's top students. An attendant of Daikoku Private Academy, Light's genius-level intelligence caused him to become bored easily; while daydreaming in class, he witnessed a notebook inexplicably fall from the sky.

While out on patrol, Deku located the source of the drug's power, a girl named Eri, before meeting Kai himself.
The World Hero organization was able to formulate an effective strategy due to Deku's intel. After learning Eri's role in Kai's plan, the heroes launched a preemptive attack against the Shie Hassaikai and managed to defeat Kai before rescuing Eri. Without Deku's chance encounter, Eri's quirk-erasure power might've prevented anyone from ever coming to save her.

He batted the attack away with a flick of his wrist, soundly defeating Frieza to save the Earth yet again.
