So Hachina snuck onto the boat with the shipping containers. Considering the Kakerou match, he may look to set up some failsafes if Gakuto ends up losing.
I wonder what strategy for placements Kaji will opt for, assuming he'll convince Gakuto to let him decide placements.
So Hachina made Gakuto protest in order to get Kakerou to load the containers with weapons to the ship, narrowing down the search for the container with the missiles. Nice.
The tablet and the screen may be safe but that doesn't mean Lacy didn't plant an external device that helps him determine Gakuto's placement. Heck, even a small camera installed in the ship beforehand would do.
I think it's woman but the author is pretty bad at drawing woman. As if he didn't study their anatomy and is applying the same principles, adding woman features after that.
