Headscratchers / Kekkaishi

• What's with Shion's outfit? It's kinda weird.
  • What ever happened to Shion period?

• So who is Tokine's Grandfather and Yoshimori's Grandmother? They are never mentioned once. Just who did the 21 Generation Kekkaishi, (Tokkiko Yukimura and Shigemori Sumimura), marry to then have Tokine's father and Yoshimori's mother? It's even implied how in the past, the previous two Kekkaishi from always working together, has grown feelings for the other one, but what happened to their partners prior to the main story of Kekkaishi that they essentially don't even exist?

  • I think they died and that there was some kind of that happened between the two families.
