Spoiler for ep10:

so in the end no one guessed right...who would have guessed that yorito is a golem created by aono ~ but still it wasnt explained if he was created in the past or present (which is imo an important piece of info as a measure of aono's manipulative power) ~

I think alot of people were speculating that Yorito was created by several eps back. As for when he was created, I would say it was 3 months ago, which was the incident that led Aono to being hospitalized.
