Gacha Girls Corps manga volume 3 features story by Chinkururi and art by Syuu Haruno.

After reaching the royal capital, Heihachi's party had a pretty rough time. First they fought in the arena after their mage, Estel, picked a fight with the hotheaded hottie, Dhius. Then, they farmed for Magigems day in and day out, not resting for a moment. So, is it finally time for them to take a break? No, the only breaking going on is the guild breaking the news that the party's gotta raise their rank or there'll be trouble—trouble for the guild, that is! Roll with the party as they do some Rank Up Quests, earning them access to a shiny new dungeon. Maybe they'll even answer the age-old question... Is it wrong to roll for pick up girls for a dungeon?
