Natsume is localizing the PSP version of Kemco's Mystic Chronicles, a retro-style RPG developed by Kemco. Yes, Kemco's back, and has been quietly releasing RPGs on iOS and Android for a while! In fact, Mystic Chronicles was one of those mobile releases. Siliconera notes that it was called Fantasy Chronicles on iOS, and featured what appears to be a different translation.
Mystic Chronicles is a turn-based game in which protagonist Lux and other characters are accompanied by AI "guardian beasts," whose assignments and basic behaviors can be set by the player.
The PSP version is due this summer, and we hope for Natsume's sake it'll be downloadable on Vita immediately.
