Mystery! The Sword-Consuming Assassin

Rukia's opponent, Jinnai Doko, reveals that the unique blades the assassins are using are called bakoto, swords that consume the user's spiritual energy to increase their strength. Jinnai eats his bakoto to increase his power and fire blades from his back. Uryu fights Kuzuryu, who uses his bakoto to transform into mist. Chad fights Genba, who uses the same rock wall-forming bakoto a previous assassin used. Chad repeatably destroys the walls with his energy blasts, but Genba fuses with the walls to attack Chad from behind.
