Princess Gold

Elijah never expected a monster to appear at his school and attack the students, let alone get killed by it. He also never expected to get Isekai'd as a Princess. Now he has woken up as the heir to the Advantian throne, and with it, he must start a new life. One filled with political turmoil, new friends, magic, danger, and a healthy dose of monsters. He is just Level One, but he must level up quickly if he intends to survive for long. Can he trust those around him enough to help him? Or will he suffer at the hands of the incoming battles? — Description from novelcodex.org
