>>280399732it's from this week's chaoter of shinobigoto
the guy he's fighting is trying to rattle him up by pointing out stuff about his social interactions and future with the girl he's protecting as the MC has baf social anxiety which has shaken him up in the past by distracting him during fights, but the technique he's been training in is to set aside stuff like that and focus on the fight which is successful when he does what's in the image
he also learned a fighting technique too, but that was just an extra thing after training in putting things to the side
