Isuzu has a low remodel level, at level 12, and her upgraded form, Isuzu Kai, comes with some desirable starter equipment; it's usually ripped from her and given to some other girl. She also gives a +5 AA bonus when fed to another ship. This has led to some admirals doing some very cruel things in the art.
In the present (4/2015) metagame however, this practice has mostly given way to more efficient methods and is rarely practiced.
