Arc 2The Ten-Year Championship
Leo survived the Six-Academy Joint Championship alongside Alice while continuing to develop his body and investigate how nuclear material affected his Shadow Talent. In the tournament’s final year, thousands of apprentices surrounded their cave, and Alice charged out with Leo following her.
- Nox attacked Leo at the volcano, but Ice Woman and Gru helped him survive until Purple Flame Academy’s reinforcements arrived, after which Leo reunited with Samatchi in Tiyama City.
- Samatchi taught Leo elemental wizardry in exchange for a promise to help Nigel, while Gru trained Leo to strengthen his body and raise his defense.
- Leo experimented with toxins, modified his tonsils, and eventually reached 100 defense, then graduated from Gru and trained by fighting beasts outside Tiyama City.
- Gru summoned Leo for the final apprentice selection, where Alice told him they would team up for the Six-Academy Joint Championship, and Leo bought equipment before the tournament began.
- Leo and Alice entered the deadly ten-year tournament, killed rival apprentices, and confronted Adelaide and his Black Skull Academy team.
- Leo killed Adelaide with his lightning-enhanced greatsword, then Alice unleashed Fire Elemental Spirits to break Soul Death Knell Academy’s encirclement and protect them.
- Leo studied the atomic bomb he found in Adelaide’s ring and conducted uranium experiments with Alice, discovering that merging with his shadow after it absorbed nuclear material seemed to accelerate his evolution.
- As the tournament entered its final year, Leo modified an atomic bomb with wizard runes and an energy crystal, then he and Alice prepared to face thousands of apprentices surrounding their cave.
