Reinforce Zwei

Reinforce Zwei also rendered Reinforce II or リインフォース・ツヴァイ) is a Unison Device created by Hayate Yagami to succeed Reinforce (Eins). Although Reinforce Zwei is significantly smaller than her predecessor and most other characters, barring Agito, at around 30cm, she is capable of shapeshifting into the size of a normal youngster, which consumes a lot of mana and is hence impractical for use in combat.
