Actually, I think this book should be called The Princess of Azure Thunder. It's a slow burn, and the plot probably won't fully unfold until the third or fourth volume.
Normal synopsis: The protagonist transmigrates into a Thunderwolf Wyvern, then signs a contract with a princess, setting off a series of events.
Abnormal synopsis: One day, the Creator got bored, picked a hundred people, and tossed them into another world to fight to the death for fun.
Shameless synopsis: My contract partner is a tsundere blonde princess. Jealous?
Qidian-style synopsis: Nine heavens of thunder, majestic and mighty. I draw it forth with my sword and gather it within me! When she meets him, this world will surely resound with a symphony of swords and azure thunder!
P.S. The author is a high school student and only gets a break every two weeks, so don't expect frequent updates.
P.S. 2: This isn't the world of Monster Hunter, but some monsters from the series will appear.
