So today I unlocked NoNoNo by doing missions.
I guess to unlock her you would need to get at least 5 Quests to max level.
Also, it seems many of the trophies are about getting Quests to max level. I haven’t seen the list but so far I always earn a trophy whenever I max one Quest.
Then I beat Story mode on Casual using her. It’s a separate mode so it has different records and doesn’t erase the normal Story mode’s current progress. You fight the same enemies in the same places though but with different (and simpler) story cutscenes. It’s mostly about NoNoNo trying to get back to her own world.
She doesn’t have more weapons to purchase and Vamp skills, and she can’t do Heroic Drain and even Blood Recovery (which makes sense, I guess). Maybe I’m missing something, but so far I need to use items in order to recover her health. She does can perform QTE on bosses and some of them (especially against Jabberwock) are pretty cool.
I think she’s very powerful mostly because she has guns; I usually just snipe the bosses. She can also do 360-degree attack with her guns and it’s a pretty powerful attack. It’s very easy to get V-rank using just this attack and occasional melee for stronger opponents. Her normal triangle melee attack conveniently breaks guards, too.
I haven’t been able to make her dance with the zombies though. Maybe it’s just for PV but I somehow doubt it. I guess it has something to do with successful Cool Combination, but I’m not good with the timing… ^^;
