For those who still wondering about Himemion, there is a person that post this in 4 chan : Himemon otherwise known as Himeo.
A demon of knowledge. Granted impartially to the knowledge of insects, wildlife, and nature. He willing gives but askes of twice in return. He's a pretty chill dude as long as you make payments on time. Expect to lose a pet or two.
Does not like the force of inhumanity or the burdening of others. However, he does make exceptions in the case of his own benefit or for things that enrich or befit the growth of nature. A couple worthy seeds and bones can easily summon him. The worth of said seeds and bones are for you to discern.
