Seashell Magic

Seashell Magic (しせる まじく, Siseru Majiku) is a form of Caster-Magic invented by it's only known user, Cyrus Arc. The magic allows the user to grow seashells of various durability from any area within a 2-mile radius where organic matter is present.

Strengths
Seashell Magic's main strength is the wide range of seashells that the user can generate, from simple ones that have no real purpose (for novices), extremely hardened and rounded ones (for shielding), and incredibly sharp ones (for piercing). The user's ability to generate these Seashells near the area near an opponent or on the opponent himself/herself is another massive advantage of this magic.

Weaknesses
Seashell Magic's main and most crucial weakness is the great toll it can take on the user's magical power. The stronger, bigger, more durable, or sharper the seashell, the more the user's magic power is drained. Thus, this magic is only favorable to those with a large magic power, or those with their Second Origin awakened. It is incredibly perferable to have the user be someone with both.

Trivia

 * It is Vitus's brainchild, created after he cut his foot on a seashell during a routine trip to the beach.
 * In order to research for this fruit, the author spent most of his last beach trip studying seashells in general, with not too much success when it came to large or sharp ones, sadly.
