You came to Akihabara for the same reason anyone does: to celebrate your love of anime, manga, cosplay, Tech, and all the communities around them. Your friend did, too. And then he disappeared.
You found him in a back Alley, unconscious and Bleeding. His attacker, a sinister figure straight out of a horror manga, came for you next, Slamming you to the ground with inhuman strength. And as you lay dying, a mysterious young Lady knelt beside you, bit her lip, and offered you her Blood...
Now you're one of them, a Shadow soul. You have Super strength, stamina for days - and a Deathly weakness to sunlight. On one side of you, there's niro, a covert Agency dedicated to hunting down paranormal threats throughout Japan. On the other, there's a family of Shadow Souls, including the killer who assault you, his rebellious sister, and enough arguing relatives to ruin a holiday.
In the middle of it all is the town you love. Your friends, The self-styled "akiba freedom fighters," like to role-play as town peacekeepers, but they're in no way ready for what's coming next. It's up to you to master your power, learn all you can, navigate the hidden world of supernatural politics, and ultimately choose a side - before all-out war blows the town apart.
