Edit: I found the explanation in text!
"Nomi" （「のみ」） is a special term that refers to some monsters. If a monster is a "nomi monster", then it means that the monster cannot be Normal Summoned or Set. It can neither be Special Summoned except by fulfilling a special requirement. Examples of Nomi monsters include "Armed Dragon LV10", "Doom Dozer", and "Raviel, Lord of Phantasms". You can identify a nomi monster because it will have, "This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by..." in its text. It is also to be noted that the Special Summoning of these cards can only be done while the card in question is in the owner's hand unless stated otherwise in card text.
"Semi-Nomi" is a term that refers to a special sub-group of monsters. If a monster is a "Semi-Nomi Monster", then it means it must be Special Summoned by its listed effect before it can be Special Summoned by another effect. "Aqua Spirit", "Harpie Lady Sisters", and "Black Luster Soldier - Envoy of the Beginning" are all Semi-Nomi monsters. You can recognize a Semi-Nomi monster because it will have, "This card cannot be Normal Summoned or Set. This card can only be Special Summoned by..." in its text.

In other words, this is not true.
