Senku chuckled lightly and without a word, summoned from his arms band a length of silk rope he had from the wedding. He held it with his teeth as he reached back, pulling his hair down into a ponytail at the base of his skull. His hair was getting pretty long at that point so it was definitely falling to his shoulders. It would be longer if it wasn't tied up.

He tied it off with a bit of an unusual knot on the top of the ponytail, so the little ends could be seen, instead of hiding that under the ponytail.

"Not really a magic trick." Senku snickered. "But it's a pain in the ass if I don't condition it." He didn't really care to. "If I did that it would just fall to my shoulders." He paused. "Well maybe longer. I need a haircut."
