Battle Game in 5 Seconds (Season 1)

Battle Game in 5 Seconds (出会って5秒でバトル, 2021) is an action anime series you can watch online on iFILM. High schooler Akira Shiroyanagi cares about nothing but video games and konpeito candy — until one ordinary morning he's dropped onto a strange battlefield by a mysterious girl named Mion.

Mion tells the people she's gathered that they no longer exist in any record. Each has been handed a random superpower and turned into a test subject for someone else's experiment. Akira's ability looks worthless at first: it depends entirely on how his opponent perceives him. But his cold, calculating mind makes him the deadliest player on the board — he wins not by force but by reading other people's powers and bluffing several moves ahead.

The show adapts the manga by Saizou Harawata and Miyako Kazu, with Ayumu Murase voicing the lead. Across twelve first-season episodes the fights play less like spectacle and more like chess, where victory goes to whoever cracks the rule behind an enemy's power first. It clicks for fans of Death Note and other mind-game anime. Stream every episode of Battle Game in 5 Seconds online on iFILM.
