Hello! Unfortunately, I only finished Penelope and Mackenzie from the Touch Detective set. They were made back in 2015 and I have since moved on to other projects, so I will not be revisiting them. Thank you for your question! ^v^
Yes, I've heard of that too! The new detective character (Shiro I think?) is SO cute! But last I checked it was only available in Japan and there's no English version :"( I'd still love to play it!
