His Kingdom for a Horse (S01E47)
Calumon discovered Jeri deep within the D-reaper's core. Though she opened her eyes, she didn't respond to him. Meanwhile, Takato was trying to persuade Mr. Katou, Jeri's father, to let go of his anger towards her. Yamaki was busy creating an advanced version of the D-Arc, which he named "Grani," inspired by a legendary warhorse, intending it to be Gallantmon's new mount. Jeri began to have flashbacks of her mother's death, mumbling in a way that unsettled Calumon. When a new Agent appeared, Mr. Katou rushed to it, begging for Jeri's freedom but nearly lost his life in the process. Justimon and Guardromon managed to take it down, but another larger Agent emerged. Just as the situation seemed dire, Grani appeared, allowing Gallantmon to mount it and charge into battle, ultimately destroying the threat.
