Baka to Test to Shoukanjuu‎ - Volume 10.5, Me and the Future and Summoned Beasts

Su Yun came to a comprehensive world that was about to collapse due to a mysterious recovery, but he didn’t panic at all.

Because, he can edit the stories of the two-dimensional girls and broadcast them publicly, and gain enough prestige by publicly executing the girls, and then he can…

So…

“Artoria, I am your previous life, King Arthur!” Su Yun, who was in the form of a dumb haired king, looked at Artoria, a foreign student with a bewildered face, and said valiantly.

“The evil spirit, that’s me, that’s you! Tokisaki Kusan!” Su Yun, who was transformed into the elf of time, stood in front of the stunned Tokisaki Kusan, with a seductive smile on his face.

“Balzebu, the power of thunder is my power, and my shape is also the power you should have. Now, try to take out the power that belongs to you from your body! It’s called – Dream One Heart!” After listening to General Thunder’s words, Balzeb subconsciously stretched his right hand to his chest.

Morgan Le Fay, Tamamo Mae, Miyamoto Musashi, Yae Kamiko…

One after another, mortal girls who had no power before, all showed their extraordinary side to the world under Su Yun’s bad taste.

So, people really think that they do have extraordinary power, and therefore, they have really gained extraordinary power.

The world has been completely changed because of this, and the mysterious history that human beings cannot overcome is rewritten!

Even so, that was not the end.

With the awakening of the Witch Hunter System, watch how Vaan takes on the world and becomes the lord of witches.

Hunting witches does not necessarily imply killing witches if you know what I mean ( ͡° ͜ʖ ͡°)
