It was an average day in Tokyo as Yuseke relaxs on a day off. Suddenly, Boton appears riding on her oar.
"Oh no. What do you want Boton?" Yusuke groaned.
"Oh don't worry Yusuke. I'm not here to give you an assignment. Koenma just thought you should have this."
She handed him a small ring.
"Isn't that the Power Ring?"
"No, it's a ring that, instead of increasing spirit power, increases physical power through height. You can only use it once a day though, so whatever size you choose, you must stay that height for at least one day before you can return to normal. Use it wisely!" Boton said, riding away.
Yusuke slipped it on and said,"Might as well try it now."
He goes to the outskirts of the city and concentrates on growing.
