A pretty simple play on words here. I thought it might be a little fun if the weapons he was dual-wielding belonged to other characters who’re familiar with wielding multiple weapons (at least in their source media). Zoro famously uses three blades, and I’ve been told Tengen uses two large blades chained together like nunchuks, which I think is close enough.
Obviously any new demons coming into the Studio would not need to be dealt with in the same way as how they would in Demon Slayer. For Tanjiro and the others, training like this is probably more useful.
Tengen is the second of three characters who tied in my last First Shoot poll on SubscribeStar. Since I don’t watch Demon Slayer I don’t really know much about him, although his headdress is annoying to draw so I don’t expect to do much with him (or, if I do, I’ll probably be using his less common hair-down design). His random partner is Yuki, the snow girl from Interviews with Monster Girls. Yuki reminds me a bit of Tengen’s wives, or what I’ve seen of them, and I think she’s a suitable partner here.
