Unless you can read JP, you will most likely have to guess and if the guess was wrong just brute force it by repeating the stage as many times as necessary. When you loose due to wrong answer the stamina is returned so you can try as many times as required to get the good result.

As far as looks go for this event, Kudzu is very nice. Has that pseudo fox girl look which I do like :3
Very nice.
The 6* this time looks great as well (unlike Plum from the previous event). Really like the design and how she turned out. Her skill are rather .... specific, and I guess it might work in a very narrow, hyper specialized team that has bunch of DMG buffs and several girls with Pursuit.
I`d be happy to get this girl purely for the looks, never mind what her skills do
