you is often shortened to "u". u is the 21st letter of the alphabet. Today is Monday, the first day of the week. There are seven days in a week. 21 - 7 = 14. The 14th letter of the alphabet is "n".
The character in danger is called Chiyo. "c". What else begins with c? That's right, calle - one of the most common words from the now defunct reCAPTCHA v1. The most recurring letter in calle is "l". Speaking of recurring letters, "e" has the highest relative frequency in all of English, at a staggering 12.702%.
Which brings me to my final conclusion: "u" "n" "c" "l" "e". The answer is uncle.
