Tokyo: I'm Being Held Hostage by a Witch

Natsuki, who went to Tokyo to study abroad, accidentally awakened the system, which can open the door to two worlds and guide the arrival of powerful people from other worlds. The evil witch forced me to teach her science. The villainous princess forced me to help her govern the country. The Queen of Hell forced me to help her buy modern weapons. The dragon girl forced me to feed her never-ending belly. "You evil girls, you treat me like a kid and force me to work for you." Fourth Girl: "Did we let you work in vain? Didn't we give you gold? Didn't we give you a blessing? Didn't we teach you magic? If you keep talking nonsense, I'll eat you." Xia Mu: "I won't talk nonsense anymore, don't eat me." The fourth girl forced him into a corner with a smirk, licked her moist lips and said with a smirk, "I will 'eat' you even if I don't talk nonsense."
