Time to book your flight, son!
No, Koakuma herself doesn't HAVE any ultimates or anything like that. She's not special enough to get one :<
Instead, she's a really, REALLY big mage. And by really big, I mean she has a crapton of spells, probably the biggest list of skills out of the entire cast of both playables AND temporary characters. So what does she have? Let's look!

Yeah, that is a huge list...and to top it off, we haven't even gotten to the Good and Bad stuff for her!
The Good:
*As expected, Koakuma has very high MP and Magic.
*Koakuma's weapon, Black Bible, has double attack on it. What makes this so particularly useful is the fact that Black Bible has 80 Attack, +25% Critical, AND a 40% chance to inflict Instant Death when it hits.
*Koakuma halves Magic damage (!!!), is immune to Absorb, and absorbs Shadow.
*Koakuma has a vast library of spells to choose from for any given situation.
*Koakuma comes with the Low Risk armor, which gives +50% resistance to ALL negative status effects.
The Bad:
*Koakuma's spells also costs a lot of MP to use, making her run out of MP very quickly...
*Koakuma is weak to both Holy and Mystic.
*Contrary to her very high MP and Magic, Koakuma has very low HP and Defense. A true mage through and through.
So yeah....Koakuma is pretty good, but even so, she can't save you from everything!
