Compete
Stand on your older brother. Now stand on your older brother again. You wish to stand on, and above, your older brother. You compete over and over again, to stand atop your older brother.
きょう, けい
きそ
None
You compete with your older brother because only one of you may go to きょうと. Whoever stands on top the most gets to go to きょうと, so you must compete for a spot.
