I always thought that である was a way to replace です, or the equivalent of
turning "noun" into "being a noun". However, In this ひぐらしのなく頃に fan art
piece,魅音 is saying

> ずっと沙都子の味方でいさせてよ

Which I think means "Let us always be your allies, Satoko"

The でいさせて looks like the causative て form of でいる rather than である. Is that
because 魅音 is talking about herself and her friends, sentient beings, and
therefore でいる should be uses over である?

question
verbs japanese-to-english causation
である vs でいる for turning nouns into verbs
でいる is "the progressive form of だ", so it means "to be being X", "to
stay/remain X", "to continue to be X". It has little to do with である.

  * 沙都子の味方でいる  
to continue to be Satoko's ally

  * 沙都子の味方でいさせる  
to make [someone] continue to be Satoko's ally

  * 沙都子の味方でいさせて(よ)  
(Please) let [us] continue to be Satoko's ally
