Since then, I have continued to take on new challenges for the past 25 years, so please continue to support Final Re:Quest The Movie, RETROGE, and The Girl from GUNMA!
However, these hidden bosses are so insidious and strong that they will make you cry, so there's no need to force yourself to defeat them. They are some of the most nasty in SHMUP.

Weeks have passed since "THE GIRL FROM GUNMA KAI." During early access, the hidden boss was discovered in no time, so we added an extremely difficult hidden stage and boss, but this time it seems that no one has been able to reach it.

By the way, "THE GIRL GROM GUNMA KAI" is easy for beginners to increase their remaining lives. However, the hidden stages are so difficult that they will completely destroy the remaining lives of advanced players.
