Kurozuma Wataru drinks Musahino milk.

Musashino Milk (ムサシノ牛乳 Musashino Gyūnyū?) is a milk brand that was originally introduced in the Toaru Kagaku no Railgun anime adaptation[1] and is later popularly used in the second Toaru Majutsu no Index anime adaptation.[2]


Not much is known about the brand, however, several female characters seem to enjoy the drink in both franchises. Most infamously, it is often associated with female characters with large breasts.

The tagline of the product is: "When it comes to milk. It's gotta be Musashino!"[3]

In the anime adaptation, the milk is first introduced in the Big Spider Arc, where it is prominently featured as Kurozuma Wataru's preferred drink.[1] Later, after Wataru comments about Konori Mii's large breasts, she states that it is because she drinks the milk anyway. The final episode of that arc during the epilogue shows Shirai Kuroko sipping the milk.[3]

The milk is shown for the first time to replace coffee milk as Tsukuyomi Komoe's preferred drink after bathing in a bathhouse. Here, several characters, usually after a bath, drink the product.

In the second special, Kiyama Harumi, Saten Ruiko, Shirai Kuroko, Misaka Mikoto, Uiharu Kazari, and Konori Mii, all indulge in the milk in an attempt to get larger breasts, whilst staring at the sunset. At the same time as this, loud and incredibly inappropriate burping sounds play.[8]
