Thank you, Wikkelsoee!
Let's list what we see in the emblems. Can anyone translate what's written in them?
Rin:
- kurikara
- two flame horns with two red pupils, which looks like they were two red-eyed demons
- a key
- a black shape which doesn't look like anything but has something like a flame tail
Yukio:
- two pistols shooting blue flames or smokes, the smokes have a green ball each
- two crossed bullets
- a test-tube with red liquid
- a pair of scales with bible on one side and something like green plants on the other
- a dartboard
- a crescent
Shiemi:
- basically it's a plant and flowers ornament
- a circle of thorns
- in the middle there's white and red something that reminds me flower petals or flames or symbols
- a leaf with greenman in it
Mephisto:
- the exorcist symbol in the middle
- two hourglasses, one upside-down
- a clock showing midday
- tacky pink cloth
- ornamented golden heart with probably Mephisto himself in both his human and not-human versions
- ... and lot of hearts
- supporting the heart are baby angel and a demon with bat wings
- latin-like text about god's sons and mercy (probably)
Bon:
- it's probably full of Buddhist symbols, like that golden circle with arrows
- a sword (kurikara?)
- a flame, I think, surrounding the sword and the circle like they were in a (smoking) vase
Renzou:
- oh my, a girl in a rabbit costume
- pink hearts
- pink flowers
- something in the background that looks a little bit like a compass
- "affection & omniscience". I wonder what "omniscience" is doing there.
Konekomaru:
- two cats, one with a green ball instead of a tail
- compassy thingy with text in a green rectangle
- flowers
