EXPLANATION TO THE PUZZLE
Ok, so to prove to all of you that the order puzzle IS possible to solve (and not so hard to) I will explain to you how i solved it. Once you have all the food, hints and characters, you can start the puzzle.
I'll number the desks from 1 to 5 (beggining from the wall) and the clues from 1 to 10.
Once you click on the 5 desk, the main hero tell us that he used to sit there. He also told us that his favorite is FRIED RICE and that his sign is SAGGITARIUS. So we found out who seats at desk 5.
According to clue 7, CATRINA sits at desk 4 and at desk 3 is a BASEBALL fan.
Clue 4. Bcuz at desk 3 is a baseball fan, desk 2 is a TENNIS fan and desk 4 is a VIDEOGAME fan (or the other way around, it doesnt matter). This is because you cant be both tennis fan and baseball fan.
Clue 2. Keigo can't be at desk 4 because Catrina is there, he can't be at desk 3 because 2s and 4s hobbys are discovered already, and none of them is a race car fan, so the only one left is desk 2. KEIGO is at desk 2. Desk 1 is a RACE CAR fan and 3 is a FISH CAKE lover.
Clue 5. Catrina (desk 4 ) is an ICE CREAM lover.
Clue 9. TOMA can only be at desk 3 because it's the only one available (except desk 1, which is a race car fan). That means that the only character left is YOSHIMI, and the last available seat is at desk 1.
Clue 8, Toma is LIBRA.
Clue 3. Virgo is either at desk 1 or 2, because they don't have food yet.
Tha means that TAURUS is at desk 4, according to clue 6.
Clue 1 tells us that CANCER is at desk 2.
That means that VIRGO is at seat 1.
Clue 3 - TEMPURA on desk 1.
And clue 10 - CARROT on desk 2.
So, that's it, hope you got it, ask me if you need.
