The third collaboration between author Tsugumi Ohba and artist Takeshi Obata - which began with Death Note - appears to be about a suicidal human visited by an angel.
Platinum End follows the fortunes of Mirai Kakehashi, a young boy without any 'hope in living'. The fact that an angel also features prominently in the story would suggest that Heavenly forces have his back. Presumably to help on a quest to acquire some aforementioned hope.
Find more information about the release and publication of Ohba and Obata's new manga in last week's piece announcing it.
And in the meantime, help me work out why translators are suddenly calling Takeshi Ken Obata. Has he gone and changed his first name? Or has some strange algorithm tweak left Takeshi lost in translation?
