Well, I suddenly remembered that I wanted to write an extra story. Gintama's extras are indeed indispensable for complaining. As for the content, there is a miscellany of everything, and the extras are not the main story. So please read the Gintama extras directed by someone with a mentality of being ready to be surprised at any time. If you have any shortcomings, please point them out and I will correct them immediately. After all, this is the first time I write such an irrelevant fanfic.
