Alm is an ancient mamodo that appeared in the Ancient Mamodo Arc. Mamiko is his partner, although her heart was being controlled by Zofis. Alm first appears along with The Silent Rulers in the battle against Brago; however, she does not fight and instead spectates. He appears inside the Water reservatory along with Gelios. When Kiyo and company find them, he is destroying walls, using all the power and freedom Zofis has given him he says. He says that Zofis lets them be free and do whatever they want, although there are some restrictions and rules. Alm seems to be very thankful that Zofis freed him from the stone tablet he was in. Like Laila, he never wants to go back to that world of silience and imprisonment. He engages in combat with Zatch and Tia after chasing Kanchomé through the ruins. Although, Zatch doesnt want to hurt Alm because he feels sorry for him so, he goes straight for Mamiko and Alm's book in order to burn it. While Alm's book is burning he tells Zatch that Zofis is in the tower and that Zatch will never make it through with his technique, trying to burn the book without hurting the mamodo or the human. When Alm and Gelios' books are completely burned, he only has a few seconds before he returns to the mamodo world, and reminds Zatch to be strong.
In the manga Alm is seen supporting Zatch in his final attack against Clear Note and is presumed to have his body restored and living peacefully along with the other Mamodos after Zatch has become king.
Alm looks somewhat like a clown. He has a small red ball on his nose, a purple shirt that has eight buttons, four on each side. Alm's arms (or maybe they're gloves) are red. He wears a navy blue hat (maybe it's his hair) that has four big spikes, and navy blue shoes. He also wears a navy blue underwear-type piece of clothing. Alm's eyes are big and yellow and don't have pupils. He has dirty blonde hair in a curl in the middle of his forehead and has teeth that look extremely sharp
- Alm is the first Ancient Mamodo to be shown speaking.
