Mamoru Shirono

Mamoru Shirono (城野守) is a Shield Hero of Raphtalia's World in the ancient past. He was one of two Legendary Heroes summoned to defend against the waves.

Appearance
Naofumi Iwatani describes Mamoru as young with an agreeable youthfulness. While not overly handsome, he has warm and appealing features.

In addition to the Legendary Shield, Mamoru's typical outfit includes full body armor which includes a helmet.

Personality
Similar to Naofumi, Mamoru is considered a kind person, however he is also more impulsive and slow to trust. Many people in his nation of Siltran look up to him as a source of inspiration but he also is willing to do unethical acts for the better good.

Abilities
As a wielder of the Legendary Shield, Mamoru has access to a wide array of skills. Unlike Naofumi, Mamoru does have some attack ability but at the cost of a lower defense rating.

Legendary Shield

 * Air Strike Shield: Instantly creates a floating shield for defense anywhere within range.
 * Second Shield: Instantly creates second a floating shield for defense anywhere within range.
 * Dritte Shield: Instantly creates a third floating shield for defense anywhere within range.
 * Tri Barrier: A skill which replaces chain shield, this skill creates a more powerful barrier from the three previous summoned air strike shields. This was unlocked with the Combo Barrier skill which was learned by raising the user's status with the job levels power-up method.
 * E Float Shield: It creates a shield that floats and moves along the user.
 * S Float Shield: It creates a second shield that floats and moves along the user.
 * Shield Bash: The user charges towards the target. Upon impact, this skill inflicts a stunning effect. However, on stronger opponents this only causes mild dizziness.
 * Shield Boomerang: The user throws their shield like a boomerang as a form of attack. Afterwards, the shield returns to the user's hands.
 * Portal Shield: Allows the user and their party members the ability to teleport to set locations. This is initially limited to 3 locations.
 * Confusion Target: This ability allows Mamoru to direct the attacks of highly confused and out of control targets. She has only been seen using it on the children she cared for, while they were out of control in her therianthropic forms, so it is unknown if it also affects confusing targets that are not his allied to hers.
 * Change Shield: Allows Mamoru to change the shields summoned by certain abilities, such as Air Strike Shield and Float Shield, to other types of shields. She has also shown that she can use it with Shield Boomerang.
 * Hate Reaction: An ability that attracts monsters. It can elongate the actual form and reveal opponents slightly hidden by magic and abilities. Therefore, detection can be used in cases of concealment. The hate reaction also has the effect of slightly increasing the enemy's attack and lowering their defenses, it also complicates the recitation of magic. When Mamoru uses it in his fight against Naofumi it also affects Raphtalia and Fohl, but not Naofumi, so his version of Hate Reaction seems to also affect Demi-humans and Therianthropes.
 * Karmic Overload: This ability accumulates all the damage taken by Mamoru up to a certain point, and then fires it into a powerful attack which will fire powerful black flames concentrated in a single black beam.
 * Shield Chain: It is a skill that is used after Shield Bash and its effects are unknown.
