Hypnosis Mic -Alternative Rap Battle- Launches Matsutake Hunting Event "仁義なきキノコ狩り～カタギたちにゃ手出し禁止～"

A new in-game event has launched in Hypnosis Mic -Alternative Rap Battle-, the smartphone game available on iOS, Android, and Amazon Appstore. The event is accompanied by a G-Collect gacha, a login bonus, and several other campaigns running through October and into November.

New Event "仁義なきキノコ狩り～カタギたちにゃ手出し禁止～" Now Live

It is autumn, and the leisure activity of the season is matsutake mushroom hunting. But the mountain hosting the event is said to be frequented by 半グレ (quasi-gangsters).

Asked by 退紅 to protect the participants from them, 左馬刻 heads up the mountain. At the venue, he finds 乱数 and 盧笙, who happen to have come for the matsutake hunt. After 左馬刻 explains the situation, 乱数 and 盧笙 set off as a pair to look for matsutake. 乱数 is carefree, while 盧笙 stays on guard but becomes absorbed in the hunt. Before long, the two get separated...

During the event, players can collect event points and event items by playing songs, and earn rewards that include an original event story and "SSR【松茸発見名人】躑躅森盧笙." This SSR card can also be obtained by collecting Event Tickets (Red) and spinning the "仁義なきキノコ狩り～カタギたちにゃ手出し禁止～ Reward BOX G-Collect." For details, check the in-app announcements.
