What episode is a fist superman, Yuki Rizaki, holding a tornado?

Excerpt from One Punch Superman comic book 102(4)

In the original cartoon of 102(4), there will be a picture of Saitama holding a dragon scroll, as shown below. The animated content of this cartoon was uploaded to the Internet, but it was later discovered that it was made by netizens themselves. This episode has not appeared in the animation yet, and it may be made in the future.

Judging from this screenshot, the dragon scroll seems to have some implications for teacher Saitama, who looks really serious. Obviously, these two are not "official matches", and their relationship is just ordinary.

Extended data:

The relationship between the tornado and Saitama began when the tornado first appeared in Saitama, but Saitama always thought that she was just a child and had no general knowledge. Poros after the war, a little abandon. However, the tornado said that very kindly, because he felt that it was not safe for a C-class hero to go there.

After their excessive desire for protection, the two men fought because of Saitama's spoiler. The attack on Saitama was completely ineffective. After learning the strength of Saitama, the earth was torn and Saitama was buried underground.

So on the whole, Mr. Saitama really doesn't like tornadoes, but he doesn't have an aversion attitude. And she for Saitama is only after the battle, to recognize his strength!
