Update: looks like I fell for it. After a closer inspection, the reflections on him are incorrect and Bulgy is missing entirely. How disappointing. As it stands, my assumption is it was edited by wagakyouso (我が教祖).
I found this tweet showing a photo of the Japanese Bulgy and Bertie replicas. However, something doesn't seem usual. Up until now, Bertie has been depicted by a Hino Poncho (reg. 1 51), but they apparently began to use a midibus (reg. 8 11) for him as well/instead. Unless it's an edit, I couldn't find any mention of it in the article, new files showing it, when it was done or whether it's permanent/occasional. Assuming it's real, I feel it's a welcome improvement and better than the Hino Poncho (which looked like it was too tall and rotund and not how he should look). Hopefully someone could ID the new bus and share the info so we could verify it.
