I finished Momohime's story over the weekend, and finished Kisuke's story last night. I'm now aiming for completion (all six endings, all swords forged, all enemy lairs cleared with both characters, and all bosses fought with both characters. POTENTIALLY may try the harder difficulty but we'll see). I loved getting a 500+ combo on Kisuke's Giant Centipede boss with Momohime, a battle which resulted in 1 ryo and 4000 mon (about 14000 mon).. :D
Lovely, lovely game. I'm so glad we decided to check it out!
