猫座特別公演 (Nekoza Tokubetsu Kōen, “Nekoza Special Performance”) is a fan-made anthology produced to commemorate the 20th anniversary of Kyattou Ninden Teyandee.

The book was published on December 29, 2010, and brings together work from a number of artists, with stories and illustrations covering a wonderfully broad slice of the cast.

The colophon identifies 小鈴屋 (Kosuzuya) as the publisher/circle and 小鈴ゆーき (Kosuzu Yūki) as the publisher/organizer, and that contributor page is worth including among the photos because it makes clear this was a genuine multi-artist anthology rather than one creator’s book.

What I especially love about anthologies like this is how clearly they show that the series still had an active, affectionate fan community two decades after its original broadcast. There are comedy pieces, character-focused stories, summer artwork, plenty of obscure characters, and lots of wildly different artistic interpretations of Edoropolis and its residents.

The cover alone is fantastic. It crams an enormous amount of the cast together, from the Nyankees and Otasuke members to villains and supporting characters, and really gives the whole thing a celebratory reunion feeling.

One of my favourite details comes right at the end:

「これにて終演!!」

“And with that, the performance is over!!”

followed by:

「絶対復活してやるからな！てやんでぇ!!」

“We’ll definitely come back someday! Teyandee!!”

Which hits a little differently in 2026, considering just how alive this franchise suddenly feels again. ❤💙🤍

This is exactly the kind of fan-produced material I love preserving. Official merchandise tells one part of a franchise’s history, but doujinshi like this preserve the history of the people who kept loving it when there wasn’t much official material being made at all.
