Commemorative Collaboration TVCM between TV Anime 『Gintama』and smartphone app 『Monster Strike』was released as a 「Unfinished CM」
The video is an "unfinished" version of the CM as the ones responsible for checking, the members of Yorozuya have totally forgotten about it and uploaded the video as it is.
The members of Yorozuya have been requested to handle 『Gintama』and 『Monster Strike』 2nd Collaboration original anime, advertisements and production checking so on.
However, because the members of Yorozuya forgot to check CM in the middle of making until the last minute,,it ended up with an "unfinshed" version with plenty of unreasonable correction instructions all over the place and a very unique 「Unfinished CM」which matches with the image of Gintama was released.

Furthermore, just like the way they dealt with the CM, the outdoor advertising was also left unfinished, with red correction instructions left in, while standing in Ikebukuro station and Namba station they proceed to announce the event period which is from the 2nd of September to the 6th of September.
