The fifth season of Boku no Hero Academia. The rivalry between Class 1-A and Class 1-B heats up in a joint training battle. Eager to be a part of the hero course, brainwashing buff Shinso is tasked with competing on both sides. But as each team faces their own weaknesses and discovers new strengths, this showdown might just become a toss-up.

In the years following a vicious war, the Empire of Zol now controls the land and citizens of rival Aquafa—except for Aquafa's Fire Horse Territory, where wild dogs that once carried the deadly Black Wolf Fever continue to roam free. When a pack of dogs race through a Zol-controled mine, Van, an enslaved former soldier, and a young girl named Yuna are both bitten, but manage to escape as the sole survivors of the attack. Finally free, Van and Yuna seek out a simple, peaceful existence in the countryside. But as the deadly disease once again runs rampant, they find themselves at the crossroads of a struggle much larger than any one nation.

Now, the greatest crisis ever approaches the Digital World. The X-Digimon, a new type of Digital Monster, is hunted by the Royal Knights who protect the Digital Worlds. Their master, the network overseer Yggdrasil, seeks to set in motion Project Ark to renew the Digital Worlds and create new Digimon, but at the cost of all other digital life. This new X-Digimon will seek out the answers to its own existence as it tries to protect the life of all Digimon, and in the process it will change the Digital Worlds forever.
