The couple that slays together, stays together. Maybe that isn't an actual saying, but there is some truth to it. Powerful anime couples form a solid foundation for their love by supporting each other both on and off the battlefield. Their love can inspire them to keep pushing through difficult experiences and motivate them by giving them someone to protect.
Who are the strongest anime couples who support each other through thick and thin? One commonly cited example is Sakura Haruno and Sasuke Uchiha of Naruto. Both are powerful ninja who have been training since childhood. While their skill sets and personalities are different, they complement each other both on and off the battlefield. There's also Asuna and Kirito from Sword Art Online, who are initially drawn to one another because of their mutual in-game strength.
Which couple are you rooting for?
When Chise and Elias first meet, Chise isn't capable of holding her own in battle. After some training that helps her unleash her true magical potential, she rapidly matches his abilities. Where she has raw power and quick intuition, Elias has years of experience and magical knowledge. Together, the two of them solve problems caused by malevolent magical entities that threaten the peace.
Ken Kaneki begins Tokyo Ghoul as a weak and defenseless college student, but once he enters the world of ghouls and starts to rack up traumatic experiences, his physical prowess and willingness to fight increases dramatically - his accomplishments as the One Eyed Ghoul are as terrifying as they are impressive. Meanwhile, Touka has always been able to hold her own, and is more than willing to throw down for the sake of those she cares about.
Krillin might have a reputation as one of the weakest members of the Z-fighters, but that doesn't mean he's actually weak - he's more than capable of handling dangerous opponents. His wife Android 18 uses multiple ki-based attacks to blast enemies to bits. Besides being able to kick butt, the two share a surprisingly wholesome relationship, clearly demonstrating their love for one another and raising their daughter with care.
One of the things that makes Asuna and Kirito such a compelling couple is that they're both equally skilled when it comes to in-game warfare. What's more, they both fully respect each other's abilities and rely on one another in combat.
Things get a little shaky in the second season when Asuna is kidnapped and takes a more 'damsel in distress' style role, but she bounces back to being a capable fighter in the rest of the series.
