when asked “how many timelines did homura go through?”, gen urobochi answered "approaching 100.“

if we assume that 'approaching 100’ means anywhere from 90-99 resets and homura’s "month” between her release from the hospital (march 16th) and walpurgisnacht (april 30th) is actually a month and a half, or exactly 46 days

then from doing the math we get (let’s just pick a number in the middle) 95 resets x 46 days each = 4,370 days / 365.25 days in a year = 11.96 years

11.96 years

homura spent NEARLY T W E L V E YEARS lost in time
