After that heart to heart talk, Rein and Mona continued their little date for the rest of the day. Rein took her to various places that she might enjoy like aquariums, animal cafes and restaurants. It was a fun day and both of them enjoyed it quite a lot.
Rein had already made plans to visit several more places with his sister and was looking forward to spending at least one week with her but Mona had different ideas. After listening to Rein's heartfelt wish for her to stand by his side, she became extremely motivated to train her powers.
Mona did have a very strong inherent ability but she had never really practiced it or anything. Everything she was doing with her ability was mostly instinctive and thus was very wasteful. If she could control her powers properly, she would definitely be able to become a lot stronger than her current self in a short amount of time.
