Around 2010, there was a time when anonymous donations called the Tiger Mask Movement were popular in Japan, because some well-meaning people at that time did not want to be named, so they donated various supplies to children in need in the name of Naoto Date, the protagonist of the manga "Tiger Mask Man". And now that the new coronavirus pneumonia epidemic continues to burn, similar moves have appeared.

Two mysterious people at the Iwate Prefectural Ichiseki Nursing School in Japan recently donated 100 masks and alcohol disinfectant in the name of the characters of "Oni Blade" And my wife Zenyo. School staff said in interviews that on March 23, a mysterious man came to the school and handed out a paper bag containing 100 masks to the school staff. And then learned that the school in addition to masks is also in short supply of alcohol disinfectant and other materials, he turned around and left, and after a while brought back alcohol disinfectant. The mysterious man did not identify himself, but only attached a thank-you note signed Ichinosuke Zuihito. On the same day, two other well-wishers, who called themselves my wife Shan Yi and "White Tiger Mask", donated masks to the hospital affiliated with the Ichiguan Nursing School.
After the Tiger Mask Movement, such donations using the names of anime characters have been in existence for a long time. The different names of the characters used can also be seen in the popularity of the works in different periods. The fact that the character of "Devil's Blade" was used as a pseudonym also confirmed that this game is indeed quite popular with the audience, and the fact that Ichinosuke's image with a pig's head is similar to that of the tiger-faced man may also be one of the reasons, right?
