Yoku Wakaru Gendai Mahou 4. Misa's pretty good at battle strategy and... Koyomi ALWAYS manages to do something inappropriate to Yumiko.
Kaho and Koyomi's interactions are funny.
"Can you not swim?"
"N-no. I just can't float in water..."
"I don't think you can call that being able to swim."
... Oh my. Yumiko does mouth-to-mouth CPR on Koyomi.
The Jini thing is cute though.
