Kenki, a boy banished from his party.

In response, he opts to challenge solo a labyrinth that would normally require a party.

Until now, he had suppressed a considerable amount of his power due to his struggles with restraint. But challenging solo, he realizes he can fight freely and begins to unleash his true strength.

Unleashing his true strength to finally vent the frustration built up from constantly having to hold back—his inability to do so—Kenki goes on a rampage, utterly unconcerned by the labyrinth's dangers.
