The only real advantage of keeping her in unkai is for lower ammo consumption. It  doesn't matter that much, but if you just use her for expedition duties you can save a bit. Tenryuu class has low stats and no ability to equip seaplane so they are relatively ineffective at combat combared to CL in general. It isnt enough to matter by itself but running mutsuki and tenryuu classes for barrel expeditions can save you a lot of resources. Esp if you combine them with using 2 lvl 1 ships after you get high enough to meet the requirements with just 3-4 ships.
