Please read the "Distribution Specifications" below before using or purchasing. -- ◇Introduction◇ The absolute void of darkness, "Dead Matter," swallows and assimilates all things. Here in "Ketsuwa no Kuni," there were those who bravely stood against the threat of Dead Matter. They were the "Shikenkan," who possessed the power of the elements. In the desperate battle against the darkness that swallows everything, the Shikenkan relied on the bonds they shared with their comrades. "Combination Technique," which connects Shikenkan and draws out even greater power. You, as a "Matchmaker," a user of Combination Technique, throw yourself into this battle. Only 50 days remain until the complete global erosion, that is, the world's annihilation. Amidst the encroaching darkness, you will witness the brilliance of combination. ◇Game Features◇ In this game, the story branches depending on which two of the up to 10 Shikenkan you combine. The choice of who to connect is entirely up to you, the "matchmaker." The main story is fully voiced. In battle, you'll support the volunteers by utilizing "Molecular Magic," activated by combinations of elements. "Combination Magic," which binds the hearts of the volunteers together, is the key to defeating powerful enemies. ◇Staff◇ Character Design/Original Art: Suou Worldview/Script: Nagakawa Naruki Music: Elements Garden Theme Song: "Yui Uta Hanshou" Vocals: All Jun'i Volunteer Officers Lyrics/Composition: Agematsu Noriyasu (Elements Garden) Arrangement: Kondo Seima (Elements Garden) ◇Cast◇ Hydrogen Volunteer Officer: Minamoto Saku (CV: Ito Kento) https://twitter.com/Saku0108_H Oxygen Volunteer Officer: Yasukata Eito (CV: Enoki Junya) https://twitter.com/Eito0816_O Carbon Volunteer Officer: Kasumi Rikka (CV: Tamaru Atsushi) https://twitter.com/Rikka1201_C Beryllium Volunteer Officer: Uroku Shiki Shiki) CV: Makoto Furukawa https://twitter.com/Shiki0409_Be Nitrogen Volunteer: Nanase Toushou CV: Shun Horie https://twitter.com/Nanase0714_N Lithium Volunteer: Misora Ukiishi CV: Koutaro Nishiyama https://twitter.com/Misora0609_Li Iron Volunteer: Jin Kurogane CV: Daiki Hamano https://twitter.com/Jin0505_Fe Fluorine Volunteer: Kuon Todoroki CV: Ryota Osaka https://twitter.com/Kuon0919_F Chlorine Volunteer: Ichina Shiozuru CV: Okamoto Nobuhiko https://twitter.com/Ichina0809_Cl Sulfur Volunteer Officer, Seiryu Izayoi (CV: Yasumoto Hiroki) https://twitter.com/Izayoi0302_S ◇Distribution Specifications◇ This game allows you to experience the main story's "Part 1" and "Part 2" for free. ◇Stories from Part 3 onwards (Paid)◇ By purchasing the "Combined Boys Main Story Pack (Saku, Eito, Rikka, Shiki)" within this app, stories from the main story's "Part 3" onwards will be unlocked.
