If you play in the sand at Colhen's beach, you can see Nao-chan.

Is it a summer event...? People said, 'Why don't they sell the clothes Nao-chan is wearing as cash shop items?'... I think I saw someone say, 'They must not want to make money'... 🤔 [Reward given once per account, once per character] Nao-chan is giving out bread, and a strawberry drink too, oh... I'll use it well for MPC bartering... Trading for Critical Potions with the Colhen Captain, gotta get it! Nao-chan... I'm looking forward to a bikini next time...ㅎ😊
