Senkou no Clarias

A school field trip to London ends with Nagai Towa lost in the city at night. At the train station, he finds a mysterious egg that shatters in front of him before he can do anything about it — and then loses consciousness. He wakes in Royal Capital Salem, a place that looks like London but is not. A girl named Shelly Linestad is trying to clear her father's name; he has been accused of murdering the king. Towa wants to get home. Both of them need something from the other. Wearing the Dragon Armor Clarias, he moves deeper into this world's problems and closer to the truth hidden inside it.
