Two very different anime worlds are colliding this summer. Bandai Namco Filmworks' Magical Sisters Lulutto Lilly and the long-running Mr. Osomatsu franchise have revealed a collaboration illustration that brings together their contrasting aesthetics in an unexpectedly charming way.

The collaboration art features Lulutto Lilly characters Uguisu and Azuki sitting comfortably on the lap of Mr. Osomatsu's Ichimatsu, one of the sextuplet brothers. The Lulutto Lilly team playfully noted on social media that the image marks the "first encounter between a cat lover and cat-like creatures"—a fitting joke given Ichimatsu's well-known obsession with cats and the magical girls' feline-inspired designs.

Timing-wise, this collaboration makes sense as both series are ramping up their presence. Magical Sisters Lulutto Lilly, which premiered on April 5 across multiple Japanese networks including Tokyo MX and BS NTV, represents Bandai Namco Filmworks' entry into the magical girl genre. The show is currently streaming on Tubi and will run for two cours (approximately six months) with a scheduled break in between. If you've been following along, now's a good time to catch up before the second half arrives.

Meanwhile, Mr. Osomatsu is preparing for its fourth season debut on July 8 at 12:00 a.m. JST (technically July 9) across TV Tokyo, TV Osaka, TV Aichi, and several other Japanese broadcasters. The comedy series, which has become a staple of anime since its 2015 debut, shows no signs of slowing down.

While we don't have specifics on whether this collaboration will extend beyond the artwork—such as shared merchandise or special promotional content—the illustration itself is a fun reminder of how anime's diverse genres can coexist and celebrate each other. It's the kind of crossover that wouldn't happen in typical Western animation, and it's exactly the sort of unexpected pairing that keeps anime fans entertained.

Both series are worth your time if you're looking for something new: Lulutto Lilly for magical girl action and Osomatsu for comedy chaos.
