Rohan is in Shion's mansion's meditation room.
Though it's called a meditation room, the walls are solid, and the soundproofing is perfect. The space is large enough to move freely, making it a suitable place for physical activity.
When swinging his sword continuously in the silence of the meditation room, without even the sound of the wind, Rohan feels like he's testing the limits of his concentration.
"Ha!"
Even if his grip hurts, he keeps swinging the sword. His calluses are starting to show.
He had been advised to rest right after returning from the dungeon, but knowing that the healing from the quest rewards had already been completed, Rohan continued with his training.
Moreover, with Ichinose Jun's words clearing his mind and feeling that now was the perfect time for training, he couldn't stand still.
