"Impressive."
After Snake Princess left, Tsunade looked at the design blueprints in her hands.
These were Mimi's Insect Swarm design blueprints. From tiny flies to giant Ground Beetles, and even Nano-Insects, everything was recorded inside. Many completed and unfinished products were also documented.
