Sinji Valley was one of the many valleys Celestial Mountain Academy built many years ago. They took ordinary locations and transformed them into grand and beautiful retreats, perfect for a vacation away from the chaos of the apocalyptic world.
Just like Stone Valley, which was primarily made of stone, Senji Valley is made of water. One could even say it resembled an island, as it's surrounded by water. However, with the mountains around it, the moniker "Valley" was well deserved.
It's a place where many seek refuge from the harsh reality outside. People often say that the moment you land in Senji Valley, it feels like stepping into a whole new world.
After flying for three and a half hours, Klaus and his friends finally crossed the borders of the valley, and the sight that greeted them was nothing short of breathtaking.
"This place is beautiful," Klaus muttered, staring at the picturesque scenery beneath them as they flew ahead.
