OVA
Description
Shihna Fujibayashi, also known as Sheena Fujibayashi, hails from the ninja village of Mizuho in the world of Tethe'alla. Trained as an assassin and summoner from childhood, she is the granddaughter of the village chief. A pivotal event marked her past: a failed attempt to form a pact with the summon spirit Volt caused significant casualties in Mizuho and plunged her grandfather into a coma. This failure haunted her for years until she forged a bond with Corrine, an artificial summon spirit who became her companion and helped restore her confidence.

Initially appearing as an antagonist, she received orders from Tethe'alla's leadership to assassinate Colette Brunel, the Chosen of Sylvarant, believing this act would avert Tethe'alla's decline. She confronted Colette's group multiple times, including clashes on the Ossa Trail and at Balacruf Mausoleum, suffering defeat each encounter. During these confrontations, she revealed her driving motivation: saving her own world from collapse. Her role shifted dramatically after an incident in Luin, where she sustained injuries protecting the town from Desian forces. This act earned her trust and led her to join Colette's group, aligning with their mission to find a solution benefiting both worlds.

Her personal journey centered on overcoming past trauma and mastering her summoning abilities. A defining moment unfolded at the Temple of Lightning, where she confronted Volt once more. Corrine sacrificed himself to shield her during this battle, fueling her resolve to defeat Volt and finally succeed in forming the pact. This marked a turning point, enabling her to later forge pacts with other powerful summon spirits, including Undine and Shadow. Her summoning prowess proved critical in stabilizing the Great Kharlan Tree and later creating a mana cannon to prevent its catastrophic collapse.

Within the group, she displayed a no-nonsense personality, though she gradually revealed vulnerability and deep loyalty. Notable interactions included friction with Zelos Wilder, the Chosen of Tethe'alla, due to his persistent flirtations. She developed respect for Lloyd Irving, who treated her as an equal. After exposing and defeating Kuchinawa, a traitor within Mizuho, she reaffirmed her dedication to her village and the group's cause. Following the fusion of Sylvarant and Tethe'alla, she returned to Mizuho to lead its rebuilding and enhance its standing.

Two years after the world fusion, she reappeared to aid during new crises. She intervened to rescue Marta Lualdi at the Temple of Ice and investigated allegations linking Lloyd Irving to attacks on human cities. Joining Emil Castagnier's group to uncover the truth, she maintained her role as a summoner and steadfast ally. After the final conflict, she participated in meetings at the new World Tree, underscoring her ongoing responsibilities to both Mizuho and the unified world.

Her combat style relies on paper seals for elemental attacks, healing, traps, and resurrection. She employs high agility and acrobatics, augmented by an Exsphere granting enhanced physical capabilities. Her primary strength manifests in summoning spirits for devastating large-scale attacks, channeling their mana into powerful energy beams. This unique blend of ninja techniques and summoning magic defines her role in battle.
