If you put two two pound weights on a person on the moon they'll increase in stature when they come back down. Everything is lighter on the moon so the person won't even feel the weights. Then when they come back to earth they'll have grown a whole two inches taller!
Getting a taller stature will also make you seem super sexy (せき) on the moon and back home on earth. If you stay on the moon long enough, you'll be the tallest person in the galaxy and who wouldn't find that sexy?! Huh?
Currently there are no similar looking kanji which exist in the WaniKani learning system
