Exciting New Collaboration Visual: Mr. Osomatsu and Welcome to Demon School! Iruma-kun Join Forces
The anime world is buzzing with some really cool news today! A brand-new collaboration visual has just been released, featuring a crossover between the popular TV anime Mr. Osomatsu (Osomatsu-san) and the much-awaited 4th series of Welcome to Demon School! Iruma-kun. This special artwork is based on the original creative works of Osamu Nishi and has left fans of both franchises quite excited. It is not every day we see such different worlds coming together in such a fun way.

A Grand Celebration for Two Major Hits
There is a lot to celebrate right now. Firstly, Mr. Osomatsu is currently marking its big 10th anniversary, which is a massive milestone for any anime series. On the other hand, the 4th series of Welcome to Demon School! Iruma-kun is already locked in and scheduled to start airing this April. To make things even more special, the collaboration visual shows the famous Matsuno sextuplets alongside Iruma Suzuki. They are all seen performing the iconic "Sheee!" pose right in the middle of the demon world. Seeing the sextuplets dressed up in the official uniforms of the Babyls devil school is honestly a treat for the eyes. Because of the huge response, it has also been decided that various goods and merchandise using this specific visual will be put up for sale very soon.
Looking Back at the Legacy of Mr. Osomatsu
If you didn't know, Mr. Osomatsu is actually inspired by the classic gag manga Osomatsu-kun created by the legendary Fujio Akatsuka. The story focuses on the lives of the six Matsuno brothers who have grown up to become quite useless adults—basically, they are a bunch of trashy NEETs who just can't seem to get their lives together. The journey of this modern version started back in 2015 when the first season aired. After that, we got the second season in 2017 and the third one in 2020. With the fourth season coming in 2025, the franchise has really expanded into movies and even stage plays. It's truly amazing how these characters have stayed so relevant for so long.
What to Expect from Iruma-kun Season 4
Coming to the other half of this crossover, Welcome to Demon School! Iruma-kun tells the unique tale of Iruma Suzuki, a human boy who ends up attending a school for devils. He has to constantly hide his true human identity to survive in this dangerous yet wacky environment. The upcoming fourth series is going to focus on Iruma and his classmates from the abnormal class as they prepare for a massive music festival. This festival is their big chance to move forward, but there is a catch. All 13 members of the class have been handed a very tough challenge: they all must reach Rank 4 to succeed. It’s going to be a high-stakes and musical journey for sure.
