Monster Kingdom Jewel Summoner for Sony PlayStation Portable (PSP)
An RPG by Kouji Okada (the father of the Shin Megami Tensei series),
Monster Kingdom: Jewel Summoner focuses on monster collection and
battles. You play as Vyse, a Jewel Summoner. Jewel Summoners are
people who can summon monsters that have been changed into jewel form.
While Vyse never underwent the training required to become a Jewel
Summoner, he did inherit a charm from his mother which gave him the
summoning abilities. Vyse heads off on a quest to find Shenah, the
killer of his mother.
Vyse has some support characters at his side. He travels alongside a
monster, Shateen, and will meet other Jewel Summoners, including Grey,
the son of the former head of parliament, and Lin, a prophet who forsaw
the destruction Shenah would bring to the world. The game features over
100 monsters, and includes ad-hoc wireless connectivity to battle
players or trade jewels.
