Well I found that this is from Musha Maruden, but I'm not sure how to tag it. According to the official site his name in kanji is 珀神丸大将軍, with the kana being ビャクシンマルダイショウグン (which is Juniperus Chinensis acccording to google). Idk if the kanji is actually meant to be pronounced like that for the tag
