Does gravity make me stronger?

Three years ago, Hachiman Hikigaya transferred schools due to family reasons and became a student at Haneoka Academy.
Three years later, gravity detectors around the world detected a distortion in Tokyo's gravity field. How could this be?
Even a peerless powerhouse with the strength of a million horses couldn't do that!
I saw it! At the center of the scene were gravity-based characters, each with their own unique moves, and their fighting spirit and stamina were astonishing.
Soyo: Don't talk about him (Hachiman) like he's yours in front of me.
Gao Songdeng: A lifetime is a lifetime; if it's less than a year, a month, or a day, it's not a lifetime.
Goto Ichiri: I promised Nijika, I'd bring you back even if it meant breaking your legs. (Ends band)
