Runes hold a very interesting piece of the story throughout Eiyuden Chronicle: Hundred Heroes, and Leon is a character who feels the power of the rune inside him and is sure that the Alliance is his destiny. Once you save him, he's happy to join.
After you upgrade your castle to level 2, you will see Leon collapsed on the ground as you go toward the western exit of the Castle Town. Speak to him to bring him food and water. Once he's refreshed, he tells you about his rune power and tells you he is joining you because his rune has told him it is what he's supposed to do.
