Zen, a former villian now the mysterious herald to the main hero! I gave her a toned down harajuku street look, because harajuku station is in the shibuya district (according to a quick wikipedia look-up, hehe). Her familiar, Ato, is a talking hat that becomes her second conscience - he bears a deep voice and grants Zen the ability to sense the nearby presence of any badges. Zen possesses a Parascythe as a weapon, a parasol that transforms into a scythe.

I perceived Zen as the mystery woman who, always without notice, helps the main hero on his quest to avoid "erasure". Her own story eventually unfolds revealing that she once served as host to the "Reaper's Game". I imagined her previous look to be dark and draped (a cloak maybe). Her experience as a villian allows her to drop in from time to time to present helping hints to the hero.

Is she really helping the hero or is she using him to achieve her own objective?
