Reinforce II (リインフォースII or リインⅡ) is a [[minigirl|smaller version]] of [[Reinforce]] that has been accepted as a member of [[Yagami Hayate|Hayate's]] task force in the Time-Space Administration Bureau; she even wears the [[uniform]]. She can be summoned as a hologram from the [[Schwertkreuz]], and promotional pictures for [i][[Mahou Shoujo Lyrical Nanoha StrikerS|StrikerS]][/i] show a very solid Reinforce II accompanying Hayate as well. Her seiyuu is [[Yukana]].

Reinforce II (pronounced "Zwei") is apparently solid, and needs to eat and sleep daily; she has a "room" of sorts in Hayate's bag. She holds the rank of Sergeant Major and serves as Hayate's SNCO/ Chief of Staff in Lost Property Management Division 6. In [i][[Mahou Senki Lyrical Nanoha Force|Force]][/i], it is shown that she can also take a full-sized human form, though she's still noticeably shorter and younger-looking than the original Reinforce.

[[agito_(nanoha)|Agito]] is her rival for some unknown reason.
