Fire Magic (火魔法,Himahō?) is one of the attributes of elemental magic that exist in the In Another World With My Smartphone series. This type of magic is exclusive to mages with the Fire (火属性,Hizokusei?) affinity.
Any magicians need to have affinity toward the Fire attribute before they can use fire magic[1]. To test one's aptitude with certain attribute, a magic stone can be used[2]. The magic stone amplifies and releases the user's magic power into the certain element that the respective stone represents[1]. The magic stone for the fire attribute is red colored[3]. If a person chants the element summoning spell while holding a magic stone, and the magic stone reacts, then the person has an aptitude for that attribute[1].
Spell Name
Element Summoning
The users summon a blast of flames while holding fire magic stone for testing their fire attribute affinity.
Before one can cast a magic spell, the user must have aptitude toward the element and chant the spell incantation correctly[4].Like most of the elemental magic spells, the user needs to chant the magic spell in order to activate the magic (except for null magic[5]). In addition, the user needs to understand the magic spell effect or form before they can activate the magic properly[6]. The spell incantation is compromised with three sentences which latter part is written in katakana for English words[7], which is language is alien for anyone at this world (Aside from Touya) [8].
