「一人は皆のために、皆は勝利のために―――」

期待のルーキープロト、理知的なランサーに、
ワイルドなオルタと、ミステリアスなキャスター。

四者四様、生き方も考えも様々。
それでも志はただ一つ。

"One for all, and all for victory."

The highly anticipated rookie Prototype, the wise Lancer, the wild Alter, and the mysterious Caster.

Each lives his own way, and has thoughts that are all his own. Yet, every one of them has the same will and resolve.
