This game isn't particularly hard when it comes to getting all the achievements- I did however find some of the endings to be slightly more difficult to achieve than others, so this here is just a quick and hopefully simple guide to get you all of the endings available.

****2 of Aleister's endings seem to be bugged at the moment and won't show up in the steam library as being unlocked, they are however attainable in game and so I've added them to the guide.
To unlock his bugged achievements, you need to change the language to russian before the last choice.

Obviously I recommend playing through this delightful little game by yourself first so you can appreciate the story and characters at your own pace and in your own style. For my first playthrough I like to pick options based on my own personality and playstyle and see what sort of ending I get from my choices.
I usually end up dead or whatever so that probably says something about me deep down...

For those of you who may be stuck on one or two things, or want to speed through the game for easy 100% completion (tut tut! lol) I hope this guide will come in handy!
Have fun reading and happy gaming!

One of the Darkrose triplets and all around snooty, purebred elf. What's not to love? ;)
*Note that in the first bit of dialogue it's fine to exhaust all options when talking to Lauren- I did for my initial playthrough and it didn't seem to make any difference whether I talked to her, told her to leave me alone or just go with the maybe some other time option. I only picked that choice because it seemed the less cold of the two quick answers.

This should get you all of Aleister's endings and relevent CGs. I realise that a lot of my answers are similar in each route. In my initial playthrough I tried all different combinations and got the different endings but for the purpose of the guide I went for the simplest options (imo)

These are probably the easiest outcomes to get, well at least they were (and usually are in most Otome games!) for me but I thought I'd add them in for good measure anyway. It doesn't matter what options you pick up until the last one, I just chose the quickest choices for the guide.

• Don't say anything
  
• Don't go and see Professor Goldstone
  
• Walk past
  
• Don't meet with Aleister
  
• Don't ask anything
  
• Say you were here alone
  
• Refuse security- CG

That's it for the guide. Hope it was easy enough to follow and there weren't too many spelling/grammatical mistakes (I'm tired, that's my excuse).
Thanks for reading!! ~ Tch. ~
