Beneath the full moon, even plants sleep through the hours past midnight.
In a human and youkai's trial of guts, what is there to fear?
Victim of the ultimate sin, where can you be found?

At last the extra stage. Compared to others before it this stage is a lot more organized than what you would expect. However that's only because enemy attacks come at you so fast that you have plenty of time to prepare for the next wave. Nothing is really that slow in this stage however in many cases the attacks are aimed at you so you can prepare an easy quick escape.

Keine is all about memorization more than skill. Hell her first spell is all about finding the safe zones. However this does not make her easy by any stretch of the word rather it adds to the stress of not almost requiring you to find and memorize the proper way through her attacks. But lord knows with Mokou right behind her you'll have plenty of chances to practice against Keine...

Mokou...not as bad as Yukari but definitely tougher than Ran and Flandre. It mainly comes from the fact that to beat her you...well quite frankly you have to try to kill yourself. Don't give me that look that seriously is the theme of this fight, almost all of the ways to beat her spells involve you moving all over the damn place a lot more than you would against other bosses and in many cases literally flying towards the danger is a lot safer than running from it. It fits with the whole immortal Mokou thing...but I'll be damned if I don't feel like a particularly suicidal moth that keeps dive bombing a flame. To note bizarrely enough Mokou's cool down phases feel a lot more difficult than her spell cards and later on they actually come at you so fast it's just pure twitch dodging to beat them.
