Tantei Kibukawa Ryousuke Jiken-tan Kamen Genei Satsujin Jiken Introduction

Trama in inglese

A game originally released as a free promotion for the DS version of Tantei Kibukawa Ryousuke Jiken-tan: Vol. 1 - Kamen Gensou Satsujin Jiken. This is not just a cut-out and delivery of the beginning of the game for mobile phones, but a new work that depicts the occurrence of the central event of the game from another angle.
