Sometimes it takes a otaku to bring the otaku out of you. For Keitaro... well he just needed a small push

Take one Ex-ronin, mix in one Otaku, pour in 8 ounces of silliness, sprinkle 2-3 dashes of shenanigans, serve in a goofball glass to shaken (not stirred) locals chilled or at room temperature, garnish with trolling as needed. Inspired by Lastofakind's and - Press Start Otaku! (Doin' it for TEH LULZ!)
