Found my favourite story so far.

"The desperate one-eyed and the demon's return"
This has some of the silliest bits in it, it's just a comedy skit and it's great

Side note: Succubi are funny as hell.

for real, the game's best moments are when it doesn't involve the "commander" in the event stories; there's a lot of varied characters that make interesting stories like this one.
would give this post an award but i'm broke as hecc

Any event that doesn't involve or barely involves Fuuma is good, I know he's technically Action Taimanin's protagonist, but he's such a boring character (on par with basically the average dense as hell harem anime protagonist) in my opinion, I just wish they'd find a way to reduce his involvement in the main story.

The Halloween events are generally good too, as they tend to go all out with the goofiness.
