S2U (Ｓ２Ｕ Esu Tsū Yū) is a Storage Device used by Chrono Harlaown before he acquires Durandal in A's.

Name

S2U is named for "Song To You" from Lyrical Toy Box.

Appearances

S2U mainly appears alongside Chrono in Nanoha, A's manga and A's.

Alternate continuities

In the portable continuity, both S2U and Durandal are wielded by Chrono, making him a multi-Device user other than Hayate Yagami.

In the movie continuity, S2U appears in The MOVIE 1st and The MOVIE 2nd A's, with no notable change in its designs.

Forms

Description

Multi-Device Emulated Cartridge System

In The Gears of Destiny, although Chrono does not wield a Device with Cartridge System, he is a multi-Device user, and hence the special program cartridge is "reprogrammed" as an install program named Ostwind (オストヴィント Osuto Vinto, Ger. "East Wind") for his Storage Devices (without specifying S2U or Durandal) to emulate the cartridge effects. Its name is presumably a reference to the anti-aircraft tank Ostwind.
