I just love it. The songs are great. It's great to see how they give the actual game vibes like the coins, boosts and the writings 'GREAT' or 'MISS' or 'PERFECT' or 'GAME OVER'. The story is great. It starts.of as a light and funny season ( I bet no other season will make anyone laugh this much) and then turns deadly serious with the comedy still maintaining.
One major character development is emu. He starts off as a character who trips over nothing literally every 30 seconds. But with time this frequency decreases but still he is a funny character. Each character get their focus and with time grow a will to save others.
Another example is poppy. At the beginning, she stars off as a bubbly heroine with a human disguise self as asuna. She didn't affect much of the plot of the 1st arc but turned to be one of the most important character near the end.
Then the creative thought of putting game and doctor motif together. In game, life can be continued right after death. But real world us different. One death means it's end of normal life. But doctors try their best and in most cases help prevent death as much as possible. So now they're fighting computer virus kinda like the way they fight real life viruses.
With 45 episodes, this is the shortest of all neo heisei seasons but the best to begin with.
