Sena (, Sena) is a playable character in Xenoblade Chronicles 3. She is a soldier from Agnus.

Appearance and personality
Sena is a girl with a small physique and dark blue hair. The tips of her hair as well as certain lines along her body glow in the same blue light as the gem on her chest, which appears to be a Core Crystal, similar to a. She wears short denim shorts and a belt as well as a black crop top and a small denim jacket. Additionally, she wears gloves and boots with white plating, a color associated with the military of Agnus. During her time as a soider, Sena wore a short sleeved chestplate, with white sleeves, and grey pants. Her term mark is located the top of her left arm.

With her super human strength, she wields the Comet Mallet in battle.

Sena has a cheerful and energetic personality and enjoys muscle training. Despite her strength however, she is shy and lacks confidence when around other people. Sena despises fighting and taking lives from others.

As Ouroboros
When interlinking with Lanz, Sena takes on one of two Ouroboros forms: one associated with herself, the other with Lanz. Sena's Ouroboros form is a (comparatively) short, white and purple humanoid with glowing cores in its wrists. It is flanked by two great hand-like wings which may combine into a giant hammer. A thin tail-like extension hangs from the back of its head, ending in a flaming ring. The form's heels feature jet boosters, which can be used both for grounded acceleration and for extra support during feats of strength.

Like Sena herself, her Ouroboros form prioritises physical strength; it is strong enough to overturn Lambda Ferronis. The wings may be used to perform powerful physical blows both individually and when combined into the hammer, and they can additionally form large energy balls for use as ranged attacks.

Chapter 1
Sena, Mio, and Taion first encounters Noah's party at on a mission to destroy an unidentified Ether source. He battles Lanz using her Comet Mallet, but he manages to block her attack with his Shieldblade, much to her surprise.

After Guernica breaks up the fight, he questions them why they are fighting in the first place. Just as Guernica is about to reveal the identity of the party's real enemy, he is impaled by an unidentified creature's stalactite-like projectile. The creature then approaches the party with Mwamba and Hackt in both hands. The creature then tries to goad both the Kevesi and Agnian parties to fight, when they refused, he killed both Mwamba and Hackt. Enraged, Mio tries to attack the creature in revenge, followed by Sena and Taion.

Sena and the party at first had a difficult time harming the creature, during the skirmish, she thanks Eunie for healing her after she was injured by the creature. When Guernica activates the Ouroboros Stone, he, along with the rest of the party became Ouroboros. He later assisted an Interlinked Noah and Mio in defeating the creature, but not before he marks the party as enemies of Moebius.

After the skirmish, a dying Guernica explains that the party has become Ouroboros. He warns them that Moebius will be hunting them relentlessly before directing them to their new destination: the City at Swordmarch. After his death, Noah and Mio sent off Guernica before both parties made the journey back to their respective colonies.

When Mio and co. tried to return to Colony Gamma however, they came under attack by their own troops, forcing them to flee back to Melnath's Shoulder the same time Noah's group fled. Both parties decides to team up, and after each party member's introduction and their hobbies, as well as a change of clothes, the party begin their journey to Swordmarch.
