Can You Beat Fire Emblem Three Houses With Only Bernadetta!?

I love Fire Emblem Three Houses... despite not touching the game in like five years at this point. But, I didn't let that stop me when it came to doing a challenge run and with my limited knowledge of the game I figured that my best option was to beat Fire Emblem Three Houses with only one character. Now time for the question, what character? Well Bernadetta of course! Mainly because she was one of the first characters that came to mind when I booted up the game. So with that explanation out of the way, allow me to ask the question. Can you beat Fire Emblem Three Houses with only Bernadetta!? #fireemblem #fireemblemthreehouses #nintendo #anime #jrpg
