Me not realizing that I gotta actually click the inbox to see what asks I've gotten 😭 sorry for the delay!!

Oh man! There's so many ways to answer

I'm a huge fan of the Walpurgis events because of the themes and aesthetics!!
Wiki wise, I remember the Easter event super fondly cause it was the first event I actually translated and it had Spanish in it, although I've yet to fully read it actually :(

Story wise, other than my immense love for 1st Anniv. I, and it is no exaggeration, adore 2023 Tanabata 😭💕💕💕
[Huge spoiler incoming]

Lives rent free in my mind how wizards can lose track of time easily and unless in constant contact with humans, losing touch with reality is far too simple and common.
The fact that the human counterpart has alzheimer (?) (or implied to at least) and is the parallel to Rustica while the wizard parallels Chloe IS SO
Heck!! Even Rustica, despite his whimsy attitude, is open to Chloe's worries and frustrations although he himself has no idea how to soothe his sorrows. 😭

It also ends with a bit of Misuaki and I have the softest spot for those two.
The fact that Aki allowed themselves to be a bit selfish and haunt Mithra with the "I hope that you miss me, cause then it'd mean... I mattered to you"

10/10 marvelous event
I hope the song composed for Rustica and Chloe is referenced in other events or stories 😭
