Tips
Boss 
 * Node K is a night battle node.
 * This map is relatively bauxite-intensive if using Carrier Task Force.  Be sure to stock appropriately.
 * Consider sending air base(s) to node I.  The enemy installations there can be disabled either by direct damage (to ≦50% hp) or by eliminating all of their bombers.
 * Maya or Akizuki-class are highly recommended to reduce damage from Air Battle nodes and have chance of shooting down all planes at node I.
 * Around 410 Air Fighter Power is needed to achieve at least Air Superiority on all nodes
 * Due to the very long path to the boss node (totaling 9 nodes), the only LBAS planes that can reach it are the Type 1 Land-based Attack Aircraft, Type 1 Land-based Attack Aircraft (Nonaka Squadron), Type 1 Land-based Attack Aircraft Model 22A, Ginga, Type 2 Large Flying Boat, and PBY-5A Catalina.
 * Assigning a Type 2 Flying Boat to a base will increase the entire base's range by 3.  With this, range 6 planes can also reach the boss.
 * For Medium and Hard, the boss's final form contains two tanky Battleship Summer Princesses.
 * The boss has 189 Armor and 490 HP (Hard).  Consider using torpedo cut-ins on your escort fleet ships to approach the night battle damage cap (300).
 * Shelling support expedition is strongly recommended.
 * For the final kill, due to the low fuel/evasion in the main fleet, Yamato-class battleships can be useful since they are capable of outputting capped damage at chuuha.
 * Unlike previous maps, the boss changes to final form at no map gauge remaining.  Therefore, by defeating Heavy Cruiser Summer Princess while the gauge is above 0 remaining it is possible to skip the final form.

Boss Debuff Mechanism
This map has a debuff mechanic.

E-4 Debuff Requirements After triggering the debuff, the "Quest Completion Sound Effect" will play when returning from sortie.
 * Achieve S rank on 4 of the following nodes: C, D, H, I

The boss voice line will change, but her text and visible stats will not show any changes. The exact effects of the debuff are still under investigation.
