Tips

The map will stay in Last Dance once cleared, until the next month's reset. Therefore, it is recommended to do quests during pre-clear for an easier time, as doing them post-clear can make the job harder.

Node H is an installation node, where   Balloons can be deployed.

Routes passing through node E are not recommended, as they require awkward compositions (either 1 CL, 2 DD in a heavy fleet or 1 BB/CV in a light one), the node has two Ru-Flags that can potentially damage any of the ships.

This map is the best spot to farm Maruyu drops (see here).

Fleet Notes
This is the strongest possible composition that is guaranteed to reach the boss via this route, assuming LoS requirements are met. It is recommended to try the south route with this composition first.
  • Sparkling can help for lower-level DDs as it is unlikely to kill or disable all enemies in preboss nodes, which can lead to the closing torpedo salvo critically damaging low-armored DDs.
  • Using   Smokes at node G (Last Dance or post-clear only) is also a viable substitute when lacking the ETSCF.
Torpedo Squadron
Fleet Info

Fleet Notes
This solution requires more advanced gears, and might be out of reach of new players. It is required to bring an   FCF capable CL as flagship, preferably an Agano-class Kai+, equipped with:

The best comp for farming boss node, having the highest pass rate thanks to the usage of ETSCF in case a ship got heavily damaged.

The Evacuation mechanic of the ETSCF should be used if needed, with no risk on the routing outside of LoS.

Fleet Notes
Ships that can activate Anti-Air Rocket Barrage or are specialized in AACI can be used to reduce enemy airstrike damage on the way to the boss node.
  • CV(B) & BBV are recommended against CVLs or BBs, so AS is more achievable on all the map.
  • Northern Princess is an Installation that can be neutralized by deplaning her or bringing an SS(V) and force her to attack it with her weak ASW attack.

Fleet Notes
Using AOs like Hayasui or Yamashio Maru, with a   SCAMP  and Bombers may help them deal more damage
  • AV should be armed with either SPB or SPF.
  • CLT and CL capable of carrying Midget Submarine 
     
     
    are preferred as they grant additional opening attacks
