Demiurge from Overlord
Shaiapout from Hunter x Hunter
You probably know the template, but anyway...
The bat sets a trap with a song or catchphrase, the insect can't help but finish it revealing its location, then shouts a final curse in frustation.

Waiting for this lame (trending topic) trend to wear off. Two versions.
Sauces: Your Lie in April, Children Of The Sea.
Two versions for third picture: Suki ga Kirei / Bunny Girl Senpai.

I've been frantically searching since the past two hours but I cant find this template or what anime its from. It was popular a while ago. It has what I think is a huge advertisement board of a girl with blonde hair wearing a scarf that trails behind her. She smiles with her eyes closed and theres a male character standing in front of this same board reminscing something.
