Is this what shipgirls spend their pay on? Pillows of their sisters and expensive electronics? It seems we need a budget cut.
Hey, they deserve it. Quite a cheap price to be able to send girls into the ocean to face death. Also consider that they are literally "special forces" sent into the frontlines. It is expected that their countries fund them with the finest equipment and luxuries especially considering that many could die upon the first couple contacts with the enemy. Similar to Strike witches. Rank has its privileges.
