I recently watched a well known touhou series called

Koishi Komeji's Heart Throbbing Adventure, known for its gore and death.

However I noticed the "Protagonist" Koishi and her sister have the ability to bring in their "Third Eye"

and their left eye changes color as well as they go berserk with power.

Could this be a reference to Sans glowing left eye?
