That's not all. The most important thing in yesterday's show is an announcement. The other host of the show, Okonogi Tetsuro announced that he had resigned from the publisher Ichijinsha. He had been meaning to do that for some time.
Now, Okonogi is not just another drinking buddy of ZUN's. He's ZUN's editor at Ichijinsha, and his contribution to Touhou is not something to be dismissed.
* Starting from BAiJR, the very first book on Touhou universe itself, Okonogi has been the main editor of these books. You can see his name as the first editor in BAiJR, PMiSS, GoM and SoPM.
* He was responsible for the Chara☆Mel magazine (where CiLR was serialized) and its successor Febri (where WaHH was serialized), which also makes him the editor of CiLR and WaHH. Like I said, since Touhou is an important selling point of the magazines, his magazines to a large extend depend on Touhou.
* Due to his friendship with ZUN and his knowledge of Touhou, he has been responsible for conducting several in-depth interviews with ZUN. This might be the most irreplaceable part of his job.
* He also got to appear together with ZUN in other contexts. Of course, the most notable is Nikenme Radio, where Ichijinsha pays for their dinner so they can say whatever they want to the internet once each month.
According to Okonogi, the serialization of WaHH will continue, and Ichijinsha will even keep supporting the show, despite him no longer being an Ichijinsha employee. This would keep Touhou from being affected by his leaving in the short term. What about the long term? How long can Febri survive? Who at Ichijinsha would be enough of a Touhou fan to do the in-depth interviews? Can Ichijinsha maintain their relation with ZUN? There are now many unknown factors.
Touhou fans have often mocked Okonogi for the numerous typos and errors in his books. Nonetheless, his friendship with ZUN had ensured some important Touhou publications could come out in a stable environment with relatively little hassle (compare CoLA's painful journey from magazines to websites to magazines). That's also contribution.
P.S.: The most famous appearance of Okonogi might be his cameos in Ryukishi 07's visuals. A character called Okonogi can be found in both Higurashi and Umineko, and the Ryukishi-penned part of Rewrite. The Umineko version of Okonogi is even a fairly important character, whose name is also pronounced Tetsuro but with different kanji. Ryukishi 07 said he did that as a way to show gratitude to the help Okonogi offered; Okonogi was not in the know until someone told him "you are a culprit now!"
From 2012's Nikenme 3D event, the guy on the left is Okonogi.
