The OVA strips away BABEL's control and lets you see what the Children actually want when nobody's telling them what their powers are for. Hyoubu's already won the argument by this point, so all that's left is three kids trying to figure out who they are without an organization defining them. It's quieter than the TV series, more honest about what growing up as a living weapon costs you.
The three most powerful ESPers in the world are growing up. Now in middle school, Kaoru, Aiko, and Momiji continue their work with BABEL, the organization dedicated to preventing crimes before they happen. Their abilities remain unmatched, but adolescence brings new complications: stronger emotions, shifting relationships, and threats that test whether raw power alone can solve every problem. When a mysterious force threatens to strip away their future, the trio must confront an enemy unlike any they've faced before. Their bonds as a team face pressure from unexpected quarters, and the question becomes whether their connection to each other is strong enough to overcome what's being taken from them. Kouichi watches from the sidelines as always, but even his careful supervision can't prepare them for this particular challenge. This OVA captures the franchise at a pivotal moment: the Children are no longer kids, but their mission remains just as dangerous. Action collides with genuine stakes as the story asks what it means to protect a future when your own hangs in the balance.
