Plant Magic (植物の魔法 Shokubutsu no Mahō) is a Caster Magic related to the use of plants.
It is a Magic which allows the caster to create and/or control rapid-growing plants to battle. These plants are grown with various properties unlike regular ones. They have enhanced abilities that can be used in various ways during combat. As plants are a main element in this Magic, the caster can summon anything, from vegetables to large carnivorous creatures and can even utilize it as a shield to protect their self from assault. Also, Arcadios stated that this Magic (or at least the variation of it that Cosmos uses) was specifically designed in order to kill people.
