quote Mio and Mayu

No, you dun have to fight them together... You first fight he ropeman... After defeating him, you unlock Chapter Zero: The Hellish Abyss... There you'll fight Sae... Just a word of advice... Switch to your viewfinder mode when you're walking towards Mayu...

okay coolness thanks for all the helpful info okay I'll keep that inmind... waaa I figured sooner or later you'd have to fight sae... does she kill you instanly when she touches you or takes 80% of you life like in the mission mode?

I despise the three children playing hide and seek. Even though it is an optional battle, When I fought them and realized how hard they were, the door was held shut! The only way I could beat them was to run around until one started counting, the run up and get a fatal frame combo, but if i didn't move fast enough, the other 2 kids attacked me from behind.

I used 8 herbal medicines and a stone mirror in that fight T-T

The Kiryu twins Win by Far! The way they ranomly appear and don't Attack and just STAND THERE! UCK!
