I don't know. I actually find this map to be easier then everyone said it is in Hard mode.
The route to the boss can be cheesed it you sailed the safe route with the proper setup and fleet support. Go A > C > FUEL > I > L > Boss.
A's Subs aren't troll enough to be a threat, C is nothing before fleet support, Resource, I actually let me waste Lycoris Hime's planes, and L's Ne-class is once again nothing before Fleet support.
Lycoris Hime attacking my air-base is does not prevent her escort from dying. OP Ryuusei Kai is OP.
11 sorties to take her down. With Last Dance ending on my beloved Fubuki Kai Ni completely shredding all of her planes making her unable to attack and Boss support killing 2/3 of her escorts. Now a sitting duck in night battle, she gets blow away by Tone and Chikuma.
Granted, most of want I said are very RNG, but if your ships are high enough level and your equipment are upgraded enough, Taiha happens surprisingly rarely. (That or I am just plain lucky. If that is the case, I am sorry for your saltiness and suffering in this map.)
