I went back to the first chapter to the page where Momiji and Satsuki first meet. There seems to be a faint glimmer of recognition in her face. Would also explain why she took a chance on Momiji when they needed help the most.
As someone who has worked in civil engineering I am familiar with a surveyor's transit. A modern instrument though uses GPS instead of laser sighting.
The last part though was hilarious.
I'm wondering something since I read chapter 9. It took two years since Makoto put on the ring before he became a full magical boy. But then Kaito first put on the ring he became one immediately. What made Kaito so different that he he is a magical boy sooner than Makoto and without so much...
I have followed this manga from the beginning. I was concerned when it was possibly dropped after a few chapters. So I'm glad it was continued. I have really grown to like the characters and story. Looking forward to more.
