Branching Rules
Node	Split	Condition
START	A	SS-only (3 or more), or Taigei + Subs-only or Taigei + Subs + 1 CL. Weighted Random towards A (instead of B) with Taigei + Subs + DDs
	B	Any composition not going to A or G
	G	SS-only (2 or fewer), or BB≥2, or [(F)BB(V) + CV(L) + CA(V)]≥3, or [(F)BB(V) + CV(L) + CA(V)+CLT]≥1 but no DD+CL
A	C	Taigei not in fleet
	D	Taigei in fleet
E	F	LoS check (with LoS equipment equipped), but still may end up going to H. If heading to F there is the LoS animation.
	H	SS≤2, or LoS check failed. High chance if [(F)BB(V) + CV(L) + CA(V)]≥2 or no LoS equipment carried. Small chance even with sufficient LoS.
F	I	Failed LoS check for K. Small chance even with sufficient LoS.
	J	Failed LoS check for K. Small chance even with sufficient LoS.
	K	LoS check with animation. Can still possibly drift to I or J even with sufficient LoS.

• The only map since 4-4 that does not have a gauge, but even B Victory takes some work here.
• At least 3 SS are required to reach the boss.
• There are LoS checks E → F and F → K. They do not have high LoS requirements (SSVs with a couple recon planes will pass), but an all-sub fleet without recon planes will be sent to H.
• Fleet composition for clearing purposes typically are one of the three types:
  • 1 CLT + 1 CL + 1 CV + 3 SS(V) (B → D → E → F → K): Effective fleet for taking out the boss but it will have to go through node B where there's a Ru-class Flagship.
    • CV may or may not wish to equip SCAMP, as it allows the CV to act first. Try to use armored CV so that it can attack even in chuuha.
    • Saiun is probably not a good idea for clearing purposes (you want to minimize damage taken along the route). Only consider that if you're using this fleet for the monthly quest (3 S Victory at 6-1 boss).
  • All all-sub fleet (A → C → D → E → F → K): Allows the fleet to completely ignore any enemy ships that can't attack subs, however node C is pretty harsh on subs with late-model DDs and flagship CLs.
    • You pretty much want to count on cut-in attacks (at boss), so only use remodeled subs if you're using this composition. Note that you need recon planes for this map, and as SS(V) only have 2 slots, you may want to just give both planes to the same girl. You want as many submarines that are actually combat capable for this route, and yes, this means that you really need I-401 and/or U-511 (Ro-500).
  • Taigei + 3~5 SS(V) + 0~2 escorts (AorB → D → E → F → K): The shortest route in terms of number of battles. Taigei can also equip recon planes to free up slots for your SS(V)s.
    • The trade off is that any enemy ship still in lightly damage or better shape at the end of shelling phase will have fewer targets to launch their torpedoes at. Taigei (and escorts if any) also has to tank all the ships that can't perform ASW, which includes Wa-class Transport Elite at D, CA Ri-class Flagship/Elite and CLT Chi-class Elite at F.
    • You also have fewer opening torpedoes, which means there's a high chance of additional damage taken.
• Pattern 1 on node H has a chance to drop I-401 with S Victory. If you want to farm her there, 1 BB 3 CLT 1 CL 1 CV or 1 CL 3 CLT 2 CV both guarantee B → D → E → H and are good enough to get S Rank.

Requires sinking the flagship at the boss node 3 times to deplete the gauge.

• Because of the amount of Tsu-class (and elite) in this map, CAVs and BBVs should keep 1 set of Type 0 recon (else they run the risk of not having any planes for artillery spotting fire). Similarly, CV(L) should preferably use bombers in larger slots (preferably a slot of 20 or higher).
• Compositions:
  • B-F-H/I-K : 1BB(V), 1CV, 2DD, 2CA(V) or 1BB(V), 1CV, 2DD, 2CLT; Passing an unknown LoS check sends you to I, otherwise to H
