Tama here, with Toshiro! He's almost completely open for plot.
First, a bit of background. Toshiro is a Soul Reaper, passing here as a normal human. If you think your character has a strong connection to the spiritual world, however, feel free to have them run into Toshiro in his spirit form. He's stuck here, though he now has Rangiku Matsumoto (a fellow Soul Reaper and his lieutenant) here with him.
AIM is TamaEnsouka, as always. More info on his profile is here, too.
