Captain Kuro From Mars and The Mad Doctor. Captain Kuro From Mars Picture Books in English, #3

This is a landscape layout children's picture book. It is the third in the Captain Kuro From Mars Series. In this book, John's mother is worried about John and all the things he has been telling her about Captain Kuro and what they can both do. She insists it is all made up, and that Kuro is not special as John claims. She is sure that John just needs some special help. So, John's mother has made an appointment to see a local psychiatrist.
He in turn insists on treating John for an over active imagination. The doctor believes strongly that imagination is the cause for all the world's problems, and he has a cure for that. Medications. Kuro however, has other ideas. So does Prince Khuram, when he finds out. Kuro shows John the other children on the same medication, and they look very ill. So John agrees to say no. But the psychiatric staff are there to help the doctor enforce his wishes.
And soon it is mayhem. The poor doctor will not be the same again and runs from the hospital screaming. He calls the police on his phone, yelling that he needs a priest, as the hospital has just been invaded by demons. The demons of course are just the image of Prince Khuram, the Royal; Bengal Tiger, who can also do what Captain Kuro can, but louder. John's parents cannot see what John or the doctor and his staff see.
They start to think the psychiatrist is himself, mad. In the end, John's father finds out the truth about Captain Kuro and apologizes to his son for doubting him.
