''Tista'' is a 2007 Endou Tatsuya manga.

Tista Ruon is a [[ShrinkingViolet painfully shy]], awkward church-going girl that dreams of being a teacher some day. At night, she's Sister Militia, an assassin who kills criminals for the church. She has a special feature in her eyes in that she can spot a target from miles away, and each shot is sure to take only one bullet to be fatal. During the day, she is nervous around Arty, a third-year JerkWithAHeartOfGold artist. Between protecting her SecretIdentity and killing criminals, Tista has been busy.

The story is neatly contained in two volumes.
