Remember: everything Tokoyami Fumikage says is made up.

Tokoyami was training on controlling Dark Shadow during the evening. Aizawa gave him permission to train in the gym, only if he had a high powered flashlight. Tokoyami would summon Dark Shadow in the dark and use the flashlight if he got out of control. It didnโ€™t seem like much progress was being made. But Tokoyami continued to try and control his quirk to the best of his abilities.
