Autumn
[13] Hero
I've come up with a theory for what "YELL" might be. I think it's a (deliberate?) mistranslation of the letter "L". Specifically, the Japanese word for a yell of encouragement is エール (ēru), which is pronounced somewhat like the letter L in English. That being said, エール doesn't actually translate to "L", so I might just be overthinking this whole thing.
