Ladies and gentleman, welcome to Mars! WARNING! A huge battleship - Soh Takeko - is approaching fast! Takeko on the stage!
~ Soh Takeko's introduction

Soh Takeko is the alternate final boss from Aero Fighters 3/Sonic Wings 3 in the Mars stage route. She is a ghost taking the form of a gigantic mahjong tile in a schoolgirl uniform. She simply appeared on Mars out of nowhere, already knowing the English language.

She will appear as the final boss sometimes instead of Gurabura. During the fight, she will happily walk around while summoning mahjong tiles to attack the player. The battle against her is timed just like the other final bosses, and in her bad ending she will be shown happily stomping over a city.
