Shildina (シルディナ) is the younger sister of Sadeena, former Miko Priestess of Q'ten Lo, and a current resident of Rock Valley. After the events of the Volume 19 she became the new Ofuda Hero of Glass' World. __Personality__ Shildina is somewhat air-headed, easily losing track of where she is going when she spots something that catches her eye and giving away important things like the card containing a piece of her soul to a complete stranger simply because he was nice to her. Similar to her sister she also has a love of alcohol and fell head over heels for Naofumi for this reason, but also has a gambling problem. Despite this, however, she has an extremely serious side built up from the constant abuse she suffered from her family trying to make her into what they consider a worthy successor to Sadeena. Initially, Shildina resents her sister greatly blaming her for abandoning her post and allowing many of the countries' problems to get worst, but over the course of their battle, the two reconcile and are at least at the level they can be called friends. It does help that before and after their Battle Sadeena did work to eliminate the root of the countries problems that Shildina was largely ignorant to.

The Rising of the Shield Hero
The Four Cardinal Heroes are a group of ordinary men from modern-day Japan summoned to the kingdom of Melromarc to become its saviors. Melromarc is a country plagued by the Waves of Catastrophe that have repeatedly ravaged the land and brought disaster to its citizens for centuries. The four heroes are respectively bestowed a sword, spear, bow, and shield to vanquish these Waves. Naofumi Iwatani, an otaku, becomes cursed with the fate of being the "Shield Hero." Armed with only a measly shield, Naofumi is belittled and ridiculed by his fellow heroes and the kingdom's people due to his weak offensive capabilities and lackluster personality. When the heroes are provided with resources and comrades to train with, Naofumi sets out with the only person willing to train alongside him, Malty Melromarc. He is soon betrayed by her, however, and becomes falsely accused of taking advantage of her. Naofumi then becomes heavily discriminated against and hated by the people of Melromarc for something he didn't do. With a raging storm of hurt and mistrust in his heart, Naofumi begins his journey of strengthening himself and his reputation. Further along however, the difficulty of being on his own sets in, so Naofumi buys a demi-human slave on the verge of death named Raphtalia to accompany him on his travels. As the Waves approach the kingdom, Naofumi and Raphtalia must fight for the survival of the kingdom and protect the people of Melromarc from their ill-fated future.
