This thrilling sci-fi/fantasy series welcomes you to Japan, a top-ten destination for extraterrestrials looking for refuge, relaxation, a good time, or just to raise a little hell! Join one unsuspecting Tokyoite as he discovers that intergalactic tourist relations can prove to be a lot more dangerous than they seem!

When the terrifying alien Hakugin attacked a young Sho Tenkubashi and his little sister all those years ago, who was their brave - and mysterious - savior? Was it Akira's father... or Akira himself, somehow? That answer seems to hold the key to everything, and Sho is determined to uncover what really happened. Meanwhile, all Akira can think about is getting stronger and proving himself as a full-fledged member of the squad, but a spar against Sho teaches him just how far he still has to go! As Akira's past and present identity grows increasingly enigmatic, will the truth from secrets long buried ever come to light?
