Official Description

Calum Thomas Hood is university student entering his 2nd year and he has cystic fibrosis and always brings an oxygen tank and nasal cannulas. When he and his peers were transferred to Auckland, New Zealand, they were staying in a creepy, old fashioned house. When exploring the place that night, something was glowing on the bookshelf. Luke accidently touched it when all of the sudden, he and his peers were falling down from the trap door to the underground. That's when they meet an old man who is the guardian. He is given the amulet of Wind which gives him the ability to make forceful winds from his hands. Whenever his powers are used, his pupils and irises disappear and his eyes become blue.

Volume 1

Calum Thomas Hood is an Australian 23-year-old student with Aquarius-themed powers and is Raphael and Zoe's older brother. He also has cystic fibrosis. When he and his peers were about to enter their house in New Zealand, they were falling down all of the sudden. They soon met an AI who lead them to an office where they meet Sir Simon again. When he activates his powers this time, he has a light blue and black suit with blue-screened goggles and he can use his powers.

Volume 2


He is shown to have messy and curly black/dark brown hair(shaved in live-action version), brown eyes and tan skin. He brings an oxygen tank and nasal cannula along the way. He wears a black shirt, black jeans and black shoes and wears a blue bracelet on his left wrist. His sleepwear consists of a black tank top and black shorts. He stands on 6 ft. 1 and is of average weight. He has an ahoge in the manga and anime version.


He is optimistic but can be shown a little frightened at creepy things like when he and his friends were out exploring the house at night. He is also shown to be arachnophobic which makes him afraid of spiders. Whenever he gets scared, he could cling on either Luke or Michael like a koala. He can also be really smart.

He can also be concerned like how Ashton is being distant from his friends. He is also serious about his past like how he got punched on the ribs and has to stay in the hospital for a few weeks. He is also really cute like how he wrapped himself in a blanket or how his nasal cannula got loose. He can act somewhat childish like how curious is he or how he insists on watching Frozen on Netflix. He also has the habit of waking up late. He is also squeamish. He can also be easily excited when he is getting a transplant but he couldn't because he got infected 2 times.


Despite the series mainly taking place in Australia and New Zealand and that Calum is of Scottish and Maori descent, Calum is a Scottish name and he has Scottish and Maori origin. It almost didn't make sense because the twins, Zoe is a Greek name and Raphael is a Hebrew name and they both have fairly European names.

Calum's middle name, Thomas is a fairly British name which causes more confusion since Scottish and British people are not usually the same. And his last name, Hood is a Scottish last name so his name is mainly European unlike his sister, Mali who has a part Maori name.

'Calum' is Scottish Gaelic for 'dove king' and it commemorates the Latin name, 'Columbus'
