Be a Couple with the School Beauty for a Semester with a Transformation Card

[National job transfer + crushing + Kamen Rider] Xiao Chen traveled to a world where everyone changed jobs, and was a freshman undergoing military training assessment. Good news: Xiao Chen changed his profession to a card summoner. Bad news: The summoned monster is an F-class bat. Fortunately, Xiao Chen activated the Mirror Kamen Rider system, which can strengthen the contract monster and transform into a Kamen Rider. At the same time, it comes with additional experience. The more monsters you spawn, the more additional experience you will get and the more rewards you will get. I can upgrade a monster by two levels, but others can't upgrade a monster by one level. This is unbelievable! Just after Xiao Chen successfully activated the system, the mirror monster in the secret realm of the freshman military training assessment escaped. On the other side, the school beauty who was assigned to team up with Xiao Chen in the military training assessment went to the classroom to find Xiao Chen, but she did not find Xiao Chen. Instead, she was pulled into the mirror world by a strange card on Xiao Chen's self-study table, and the school beauty's summoned beast was also sucked into the card. The school beauty who was pulled into the mirror world was confused. Why did he suddenly come to the mirror world? Where has my summoned beast gone? At this moment, the school beauty encountered a monster that escaped from the secret realm of military training, and the school beauty was desperate. Xiao Chen suddenly appeared and said calmly to the school beauty: "ADVENT!" A huge black-winged monster appeared and blasted the monster with one blow. … School belle: "Can you give me the transformation card?" Xiao Chen: "No!" School belle: "What are the conditions for agreeing?" Xiao Chen: "Are you kidding? That's my transformation card!" School belle: "What if I were your couple for a semester?"
