Arc 4 of 5 in Battle in 5 Seconds

Arc 4: 4th Program

Arc name chosen by Arc Almanac, because the books don’t name it.

I’ve watched through

Season 1 stops before this arc.

What happens

The people who cleared the third program return to Tokyo for a battle among dozens of ability users grouped under observers, with only a handful allowed to go on. Killing strengthens a power, and stepping off the field can drop someone into a separate game run by an observer.
