Walkthrough - Day 2

Main Plot
Visit the newly-opened "infor!Mashun" building and talk to the informant. Go talk to Gardenia. Accompany her to the Incarners' Market in Dozing Forest. After asking for a frying pan at the market, return to the informant to get the Celebration Compass. Use the compass to open a path inside the tree in Dozing Forest. Head into the dungeon.

Go to the differently-colored wall in the middle and knock on it to learn Sorrow. Go to the door on the right and use Sorrow. Defeat the Lamenting One.

Take Gardenia home. Go home.

Guilt Events
None.

Just a Heads-Up (Day 2 Only)
Go to the SOS? building and talk to Yumi. Distribute Heads-Up Flyers to everyone's mailboxes. You get 5 Walnuts as a reward.

Raymond the Peddler (Day 2 Only)
In the Sad Birthday house, you can find Raymond. He'll peddle you a Super Ball. Refuse once to get it for cheaper. If you want him to join you later, you'll need to buy 3 or more peddled items from him before Day 5. (There are a total of five opportunities to buy from him, and one is easy to miss.)
