===Map Unlocking & Progression===
'''6-3''' is unlocked after clearing [[6-2]] HP bar.

To clear the map, the boss's flagship must be sunk 4 times.

===Stage Guide===
{{MapBranchingTable
|title = 6-3 Branching Rules
|id = 2-5
|A/empty -> B,C = * Choice node

|E -> F, G/resource = 
*Meet '''ANY''' of the following to go to F
**Amount of AV+CL ≥ 4
**Amount of AV ≥ 2 
*Go to G if CL ≤ 1 '''and''' DD ≥ 3
*Otherwise, random routing (More likely to go to F)

|G/resource -> H/resource = * Fixed route

|H/resource ->  I/empty =
* Fail the LoS check
** Random routing if the 36 ≤ LoS ≤ 38 (Cn3)
|H/resource -> J = *Pass the LoS check: > 38 (Cn3)
}}

===Tips===
====Regarding the map====
Once the map is cleared, it no longer possible to roll the final boss form.
*'''Only AVs, CLs, CTs, and DDs are allowed to sortie!'''
**Specifically at least 1AV, 1CL, and 1DD. CLT cannot be used here.
*Maximum of 2AV allowed.

====Node notes====
*Node {{MapRoute|C|red}} is a normal submarine node
*Node {{MapRoute|B|red}} is a submarine node that sometimes contains surface ships instead of submarines
**Regardless of enemies present, {{MapRoute|B|red}} is treated as a Submarine node for {{Ammo}}/{{Fuel}} consumption
**The only reason to head towards {{MapRoute|B|red}} is to have a fleet that cannot/doesn't want to face [[Submarine So-Class#Elite|SS So-Class Elite]] at node {{MapRoute|C|red}} but at the cost of an extra surface node
*A [[Light Cruiser Tsu-Class#Elite|CL Tsu-Class Elite]] can show up at node {{MapRoute|E|red}}.
*Node {{MapRoute|G|green}} can be guaranteed with 4 DDs in the fleet.

===Recommended Fleets===
AVs and CLs able to carry a {{EquipmentLink|Type A Kouhyouteki|Type C Kouhyouteki|Type D Kouhyouteki Kai (Kouryuu Kai)|text=Midget Submarine}} are advised in every composition.
*Because you can only deploy AV/CL/CT/DD, it is unlikely that your fleet win during daytime battle. You should expect the battle to last into nighttime.
*Using [[:Category:Seaplane Bombers|Seaplane Bombers]] on your AV's biggest slots can help you achieve AS and Artillery Spotting.

|-|Heavier fleet=
*2AV, 1CL, 1DD, 2CL/CT/DD
*'''2AV, 3CL, 1DD'''
*Route = {{MapRoute|A|blue|C|red|E|red|F|red|H|green|J|red}}
**Has the highest damage output at the boss, especially since the boss fight almost always requires night battle.
**Needs to fight an extra battle against a fleet led by a [[Heavy Cruiser Ne-Class#Elite|CA Ne-Class Elite]]

|-|Light fleet=
*'''1AV, 1CL, 4DD'''
*Route = {{MapRoute|A|blue|C|red|E|red|G|green|H|green|J|red}}
**The most cost-effective way to get to the boss, and guarantees {{MapRoute|G|green}} branching, which allows two air reconnaissance rewards. 
**The setup with the lowest damage output. It may not consistently get a victory at the boss.

|-|Medium fleet=
*'''1AV, 2CL, 3DD
*Route = Random:
**{{MapRoute|A|blue|C|red|E|red|G|green|H|green|J|red}}
**{{MapRoute|A|blue|C|red|E|red|F|red|H|green|J|red}}
**Has better damage over the Light fleet, and on the shortest route, can fight at the boss with better damage output.
**Has to deal with RNG. Being sent to Node {{MapRoute|F|red}} may hurt a bit more.
