- Wait for Christmas or use the cheat code to unlock Christmas content (simply skips time checks). Then buy a present for Mizu in the mall
- Same as above, but Asara and Halloween. Wait or use the cheat code
- Same as number 1, but Asu
- Kate pregnancy repeat I believe
- Not finding Klaus route. There's an event way back in the pool, where Asara suggests finding Klaus. Reject her offer
- One of the minigames. Probably the battle one from the arena. Select monsters instead of duels
- Deceiving Isabella route. When meeting Isabella for the first time, reject her offer once. Then play along and agree. After that, participate in the seduction circle party and select 'convince Isabella to your just cause' when she approaches you in the dorms
- Seduction circle party. Simply the non harem variant. Pretty much same thing as the harem option but has less scenes
- Willow arena wargame. You need to be dating Mia
There's a bug in 0.36 which allows you to start the wargame event (number 9) before doing Mia's dating events. Make sure you start dating Mia before doing the event to unlock this one.
