When they told John he was getting a new roommate, He wasn't sure what to expect. But he definitely wasn't expecting this.
What he got was a fast-talking, loudmouth, extremely caffeinated short Carribean kid.
And sure, things were going okay until the next morning when his roommate woke up the next morning.
"G'morning Alex," John muttered, stretching, still half asleep.
"What the fuck? My name is Rose, you fucking idiot." A distinctly feminine and very pissed voice responded back.
John jumped, his eyes wide, and did a double-take at his roommate. Still the same person.
"Ha, ha, Alex. Sure." John responded.
And that's when Alex stood up, came right over and bitch slapped him.

Kanda Kyoichi transmigrated to Konoha and became a temporary instructor at the Ninja Academy. Fortunately, he awakened the Mentor System.
By teaching others, he could earn rewards.
Thus began Kyoichi's career as a "teacher" in the ninja world.
Shisui: "Sensei's unique interpretation of the Will of Fire has given the Uchiha Clan a true sense of direction!"
Asuma: "The essence of the jade lies in protecting the people, with the advanced leading the way for the less experienced. Only then can Konoha become stronger!"
Kakashi: "He's my life mentor. He transformed Konoha!"
...
Years later, in the memoirs of Kyoichi, now the Hokage, he wrote:
"I honestly just wanted to be a life mentor!"
