Watch the OP in slow motion.
First we see Corpse Temple, and a white hair boy (whose visual is also revealed on this episode), then the white hair women with pointy ear at the very beginning.
Now look at Kanon's visual again in this episode. Some people are noticing similarity.

Also, this is the important hint from the manga that anime left out for those who wants to know.

Spoiler:

Corpse Temple's reincarnation spell is designed to only transmigrate his soul into a freshly dead body that belongs to same biological race as him before he became an undead.

I should also fill in on the flash back with the Wandering Raft that was cut short.

Spoiler:

The flash back in manga starts with Corose Temple's teacher talking him that she is going to treat him as an object and make him her personal possession. She then goes on saying one should not look down on objects, as at time they possess spirit's greater than human being. Then she says she sees more value in object than human being and will help him who is an object of her possession.
This part of conversation is pretty important as this pretty much tells you where Corpse Temple's philosophy on human life being toys but he treasures these toys had developed from.

I pray gard they cut no more on the flash backs with Wandering Raft in the future. Her influence on Corpse Temple is deep and profound.
