Revisiting Ex-Aid, it really is a masterpiece. Everyone is a favorite except Kuroto, though my dad loves Kuroto.
Emu Hojo and his colleagues work at Seito University Hospital. They are Kamen Riders who fight to cure the Bugster Virus, commonly known as Game Disease. Game Disease infects people who experience intense stress, causing a Bugster to be born; the patient cannot be saved unless the Bugster is defeated. To save them, the power of a Kamen Rider is required, and the disease cannot be cured unless the game is cleared. If they fail to clear it, the patient will vanish. Furthermore, the Kamen Riders have a gauge, and if it hits zero, it's Game Over and they too will vanish. The Kamen Riders fight with their lives on the line, and the existence of Game Disease is a national secret. Details on Game Disease: Upon infection, the Bugster Virus multiplies within the patient's body, eventually separating from the patient to manifest as a Bugster. Symptoms change depending on the game the patient is infected with. When infected, the body glitches, shaking and becoming transparent. The condition progresses when the patient feels strong stress or fear. If the condition becomes severe, there is a risk of the patient reaching Game Over.
