[MANGA][CBZ] Super Smartphone

Kyu Sagurada may be brilliant, but he’s taking the lazy route through high school—at least until he stumbles across a phone that can search through any and all information on earth. To curb his boredom, he starts solving local crimes and cold cases. But he soon finds out that his superphone might be the only lead on a cold case near and dear to his heart—the disappearance of his younger brother seven years ago!
