S2U as seen in The MOVIE 1st
|First app.||Nanoha (ep.7)|
|Voiced by||Aya Hisakawa|
S2U appeared only in the original series, the A's manga, and A's. As a Storage Device, S2U has a higher processing speed than an Intelligent Device like Raising Heart and Bardiche, but is unable to advise its master on which spells to cast in a particular situation.
- In its standby form, S2U appears as a black card.
- In its active form, it appears as a black staff.
In addition to serving as a weapon, S2U also appears to be capable of absorbing and storing magical items, as seen when Chrono uses it to absorb three Jewel Seeds.
