I have a couple of questions before playing.
1) Are the Christmas, Easter, and St Patricks Day events only available on their specific day, or can you trigger them anytime after that day?
2) The wiki says that some girls were removed. Are they in this final version, or are they still gone?
3) The wiki says there are some other events planned (Valentine's day, etc.). Are they in the game?
Wiki is beyond out of date.
St Patrick's Day, Easter and Christmas are in the game. Don't know about Valentine's, though.
The Christmas event is supposed to trigger every 24 days at 11PM. Location varies, as there are five different ones.
(Aiko, Mitsuko, Naomi, Utako and Yatsumi.)
Easter every 34 days.
St Patrick's Day is the odd duck here. Seems you only neeed Kei and
Sarah to be in the same room of the museum at the same time. It auto-fires.
The removed girls are not in the final game beyond cameo appearances.
Penny, Shiho, Kinu, Miwa, Yurika, Chan-Mei and Wakana were removed by poll.
Probably because they don't have ridiculous bust sizes.
