Choose
You want to get a scooter, so you have one self (oneself) and another self working together to choose. The two tiny yous sit on each of your shoulders, like angel and devil, and argue about which scooter you should choose.
Your angel self says you should choose the safest scooter. The devil self says safety is for suckers, and you should buy one that's loud and dangerous and covered in flames.
せん
えら
None
Suddenly your selfs both gasp and choose a scooter in front of you that looks like a centaur (せん). The scooter is designed like a human on the top, the bars are its arms, and the bottom with the seat and the wheels are all horse. This centaur scooter is what you choose to ride.
The angel self says, "I choose this centaur scooter because of its strong arms." The devil self says, "I choose this scooter because it looks like a badass horse monster, wooh!"
