Many Heroes fought against the powers of destruction and protected the world; years in the future the Heroes disappear and those possessing their powers, called Successors, now have the fate of the world in their hands.
After arriving at Granseed Academy, Nemo gets inducted into the Seven Knights, and meets its unconventional members; Jou Tsurugi, successor to the hero Spike, takes an immediate dislike to the weak-willed Nemo.
When the Seven Knights fight together for the first time, Gildan begins to feel eclipsed by Nemo's power.
Nemo is laid up after the last battle, with Faria nursing him back to health; while the others speculate about the dark power that overtook Gildan, Nemo and Faria end up tracking down a runaway cat.
The school prepares for its annual festival; while the rest of the students worry about finding a partner for the night's dance, Claire struggles to find a way to be useful to Gareth.
