A Diffusion Disease

拡散

Katsuhiko Tobe, affectionately known as Kacchan, faces a surreal and terrifying condition: his physical body is gradually dissolving, diffusing into nothingness across time and space. His consciousness, however, remains vividly aware, untethered and flowing through the world as he contemplates his bizarre fate and the nature of existence itself.

As Katsuhiko's disembodied mind wanders, his best friend Azami Seshimo remains behind in Japan, steadfastly waiting and hoping for his return. Their connection becomes a fragile anchor in Katsuhiko's increasingly abstract journey, as he searches for a place where he can truly exist again.
