mikogami sayo

In the final chapter, she faints at the basement after empowering the sword required to defeat the ushioni（牛鬼）. After the ushioni is defeated, the yashiki collapses after the protagonist places the final orb and escapes, presumably killing her. In the true ending which is unlocked if players final all 25 youkai (21 are visible while 4 are hidden), the youkai will allow the protagonist to return back to the yashiki but with a time limit (indicated by 8 flames which will disappear one by one over time). At there, she can be rescued by the protagonist if players go back to the basement, click on her and escape from the yashiki within the time limit.
