Kamen Rider Ex-Aid Episode 3 –BANG, That Jerk is Coming! - Live Reaction!
Warning! Spoilers!
Opening is growing on me, but still not my favorite.
Also, I find it amusing that in universe, the Bugster virus is outright called a 'Gaming Sickness'.
The episode opens with Emu checking on a young boy named Yuuki who...decidedly does not like doctors and runs off, even when Emu tries using video games to get him to open up, at which point the boy runs off. Victim of the week?
