This route is extremely economical and will result in next to no repairs and the consumption is also very low, if you are short on resources and not interested in any drops on the boss I would advise using this to farm for Roma. The Anchorage Water Oni has no fighter power however there is a formation with a Nu-Class Flagship therefor you will need some fighter power of your own. 69 fighter power will be enough for AS+ on hard mode, bring a Saiun in the smallest slot and everything else can be an attack plane. I would consider bringing one ship with an AA CI setup still since the Anchorage Water Oni has a lot of attack planes, either Maya Kai Ni in the first fleet or Akizuki Kai or a different DD in the second one.
Battle formation on both nodes and retreat after clearing K, I am going into night battle at H to get an S Rank but right now Roma drop is only confirmed on K but you are not giving up anything for this so its not an issue. My consumption was roughly 200 fuel, 300 Ammo, 50 Bauxite and I didn't need to repair in the first 10 runs. I did use my Italia who has quite high consumption but if you only use 2 CA/V in the first fleet you will use even less. Also I want to point out that this is extremely easy and the experience is quite decent, therefor I would advise using ships you want to level as much as you can so you have an additional benefit.
