Lost Sailors (海より還りし亡者) is the third stage in Ghost Sea.
- The boss, The Face, spawns at the start of the battle.
- An Oldhorn follows 16.7 seconds500f later.
- After 26.7 seconds800f, up to 5 Mesocosmocyclones will spawn, delay 25.3 seconds760f.
- After the fifth Mesocosmocyclone spawns, nothing more will come out of the enemy base.
The stage is much more straightforward than the previous one. Simply apply the same strategies you would normally use for Mesocosmocyclones and Oldhorns at the same time. Equip 3-4 meatshields, Castaway Cat (32) , Psychocat, Can Can (44), and Thaumaturge Cat. Lure the Mesocosmocyclone and Oldhorn as close to the base as you dare (maybe 1/5 of the stage left) and spam all the cats. The Oldhorn should die before The Face gets too close.
