Joint Training Battle

The Joint Training Battle is a combat training exercise that pits the students Class 1-A against Class 1-B in a series of five team matches. This exercise is also used to examine  Hitoshi Shinso's potential for the hero course. This is the first even to take place in the winter of the student's first year.

Prologue
Shota Aizawa and Vlad King hold a Joint Training Battle between their classes during the early days of winter. Each class dons their winter hero costumes and meets at Ground Gamma.

Class 1-B arrives after Class 1-A and Neito Monoma openly challenges Class 1-A to this decisive battle between the rival classes. He even reveals that students voted Class B's play over A's musical performance from the Cultural Festival.

Shota silences Neito and announces that there will be a guest for this exercise. Hitoshi Shinso is being reviewed for consideration into the Hero Course. Hitoshi re-introduces himself to everyone and explains that in order to become a great hero, he must overcome everyone else.

Vlad King and Shota begin the exercise immediately afterward. Each class chooses lots to split into five teams of four. Each team battles one match at a time inside the training field. Hitoshi is placed on a team with both classes, making two matches are five against four. Each team perceives the other as villains and must try to capture one another.

The team that captures four people and places them inside an "Irredeemable Jail Cell" wins. Teams of five still lose if four of their members are jailed. Teams start at their own bases and the matches are set with a twenty-minute time limit. If time runs out, the team with the most captured enemies wins.

All Might and Midnight come to spectate the battle. The matches begin shortly after both all students draw lots to decide their teams.
