"Systematic theology" sounds like something for professors and specialists. This manga starts from the opposite point: every Christian already has a systematic theology, whether or not they have ever used the phrase, and it shapes how they live.

The story is set in a Christian school, where characters meet the basics of systematic theology through six "keys" for knowing God. It is a manga version of the ideas in Knowing Me, Knowing God, told through conversation and everyday situations rather than technical vocabulary.

Each chapter finishes with a short recap and questions for discussion, so the book works for reading alone and also for a small group, a church class or a youth meeting.

Original story by Richard and Yuko Brash.
