Take yourself on a date! Have an adventure! Read a book! Get lost in a labyrinth! Draw a map! Buy yourself dinner and a movie! Slay that evil entity that’s been killing all the other guilds! Pet a squirrel!
One really cool feature of Fire Emblem Heroes is the credits in the lower-left corner of character stat pages. If you ever see a character and think, “wow, why does this guy look like he got lost on his way to an Etrian Odyssey game,” you can check their page and find that they were, indeed, drawn by Himukai Yuji.
The voice actors for the characters are also listed; this guy happens to be voiced by Sam Riegel (sometimes credited as Regal), the voice of Phoenix Wright!
