Within Moon Castle, after taking care of a 'small' problem, Anvis did not leave as gracefully as others had imagined. Instead, he temporarily took over the castle's Mystery Lock with the magic key in his memory.
The downfall of [Zero-Degree Ice Crystal] Pomona was inevitable. Although he struggled before his death, he had been injured, and Anvis's strength was beyond that of an ordinary Ninth Rank Professional.
Originally, Pomona planned to use the home-field advantage of Moon Castle to contend with Anvis, but he did not anticipate Anvis's profound understanding of the castle's protective array.
Once Pomona was dealt with, there was no longer anyone within Moon Castle who could restrain Anvis, which was one reason for his daring behavior.
After Duke Carrot was attacked, Pomona was the only Ninth Rank member of the Olivendi Family who could stand up.
