It's a bonus event which gives you another equipment. Anemone got 2nd place in last vote event so she had it. Another example would be Hyperloli who also got extra equipment because she got 87th place, which can be read as 'hana'(flower) And we know how much Japanese people loves words pun.
As of little girl event, it seems like she will slowly but surely fall in love with knight commander after he saved her for countless times now. Would be nice if by the end of these long event, you will get the girl as reward aside from usual FG.
