Here is the full list of all 20 Notch - there are The Innocent LunA: Eclipsed SinnerS achievements.
It seems this is the final one...
Nothing will ever separate us again
For 333 times?!
Don't let the one who loves you down
Love hates what is evil
It didn't end well...
I will remember all of these
The scars of the past are deeply rooted in your heart
She's gone, but you will live on for her
I will love you with all my heart
This is the fate from which there is no escape...
Return to the real world
Violence is happening in the house
You'll have your revenge via a pact with a devil
No one could save her life...
Meet the speechless girl and the mysterious black shadow
Murder happens in this town again
There seems to be a third person here
All the misery will end tomorrow...
What's in that room?
