Long post alert because nothing from me will be short when it comes to my WOL/OC
Hoko is really strong! Her Oni blood has already helped plenty with her physical strength, but she also trains a ton. She can lift things up to 300 kg at best. Despite not looking particularly beefy, when she flexes, Hoko's body is quite a marvel to look at.
In comparison, Yako, Hoko's younger twin sister, doesn't train her body that much as she's more efficient with magick and the arcane, but her Oni blood is enough to help her pull a rather hefty bow and keep up with her sister in adventuring.
Apathya isn't so strong. She trains herself enough to wield her arts sufficiently, but no more than that. When the need for great strength comes up, she weave in strengthening magic to get the job done, but it's not something she can maintain for an extended period of time. To get around that, Apathya carefully weave in the strengthening magic at certain times to increase the force of her strikes.
Hoko once commented: "Apa-chan's strength is like a kid having a tantrum at you, but getting hit by her in a fight is like on the receiving end of a cannon ball."
