MAL's rubric, split into categories like "Story" and "Character," is useless for an animation like this. It's four minutes long, with no named characters, no voice acting, and exactly one color: red. Two, if you count the white background. This minimalism is the anime's greatest strength, for it allows no distractions from the message: that life is beautiful. Unpredictably, painfully, miraculously beautiful.
Flawless in its simplicity and a genuine pleasure to watch, Okushita's "Akai Ito" is a work of art I cannot recommend highly enough to anyone with a human soul.
