Sloth seems to have latched onto an ancestor of Mikulia and whenever an ancestor died, the Demon seems to have jumped to the next generation. Mikulia ended up looking like Eve because of the Demon's influence before she was born. I.R. seems to have had to direct it to its vessel. Considering there is an inclusion of how it refers to itself, I am going to assume it speaks or converses at certain points with other characters (at least Mikulia).

We assume the Marlon Spoon is that unique spoon that appeared in the manga, surrounded by treasure. Mothy also said in an interview only one of the items was an actual magic tool so I.R.'s claims make sense. Since Sloth didn't have a vessel yet, she may have put Greed's in there.

Then there is the Venom Sword that sounds like it is a Snakeland design (katanas, what a surprise...) that was made somewhere else (Levianta?) so it could be a Clockworker sword.
