Ring Horror Films' Sadako Possesses Sgt. Frog in Crossover

So In this film, SGT.Frog (Keroro) Will be Sadako.

Following in Hello Kitty's footsteps, the frog-like manga/anime alien Sgt. Frog (Keroro Gunso) is the latest crossover character with Sadako, the star of The Ring  horror films. "Sadako Keroro" dons Sadako's signature eye-obscuring black tresses in two designs — she/he emerges out of a television in one design, and crawls out of a well in the second design.

Mascot trinkets of both "Sadako Keroro" designs will be sold at theaters showing Sadako 3D, The Ring franchise's first film in stereoscopic 3D. "Sadako 3D x Hello Kitty" products will also be sold when the film opens on May 12.
