Final Fantasy IV The After Years by Ichiro Tezuka
Final Fantasy IV The After Years is a light novel by Ichiro Tezuka. It is based on the video game of the same name. Final Fantasy IV The After Years was originally released in 2009 along side Final Fantasy IV, a novelization of the base game. Ichiro Tezuka, the author of this light novel, was the storywriter of Final Fantasy IV: The After Years and Final Fantasy Dimensions.
This Final Fantasy IV light novel never received an official English localization. Only Japanese language versions of it exist. I would recommend having a Japanese reading ability of at least JLPT N2 to fully enjoy it.
Light novel are similar to young adult novels. In this case, the light novel has a few illustrations but mostly contains text.
Please check the reference photos carefully before purchasing to confirm the light novel's condition.
