Start off the day by hanging out with Shinya. You will be getting awfully close to maxing him out at this point.
Confidant: Pick "I’m glad to hear that" for the first answer, then either "No, that makes senses" or "It means you’ve matured" for the second, and "He wants to win at all costs" for the final one.
At night, you will be hanging out with Mishima, with this being the final one. As usual, the responses given don’t matter and for maxing out the Moon Confidant, you will be able to fuse Sandalphon, the ultimate Persona of the Moon Arcana.
You will be asked a question during class, with the correct answer being "The Holy Grail," earning you a point in Knowledge. After school, you will be finishing up the Tower Confidant, so go and hang out with Shinya. The responses don’t matter and you will now be able to fuse Mada, the ultimate Persona of the Tower Arcana. During the evening, go to the counter at Leblanc and finish reading Reckless Casanova, netting three points in Charm.
Today is going to be a busy day, as there will be quite a few things to do. You will have a seat on the train during the early morning hours, so use that opportunity to read the Chinese Sweets book, which unlocks the China Town hangout spot on your map. During class, you will get some free time, so use that chance to read Tokyo Shrines, which unlocks the Meiji Shrine hangout spot. This place works similarly to the Affinity Reading for Chihaya, but there’s a certain randomness to it for the increase in affinity, as you don’t always get the same result.
After school, you want to go to Jinbocho and purchase the Speed Reading book, which sounds exactly like its name. Go to Shinjuku next and get an Affinity Reading for Hifumi, then go and hang out with Futaba.
Confidant: Choose "That must have been a shock" for the first response, then "You didn’t know any better" for the second, and whatever you want for the final one.
Since you did Iwai’s request earlier, you can continue his Confidant tonight, so go and hang out with him. You will get an invitation from Haru when you’re laying in bed, so decline it.
Confidant: Pick "I dunno" for the first answer, then either "I guess I could consider it" or "If you pay me well" for the second one.
You can check your TV today to see that the shopping channel has a Hachiman Belt for sale for 9,800 yen (high reduction for physical damage), so purchase it if you want. After that, head to Shinjuku and get another Affinity Reading for Hifumi, then hang out with Futaba. You will get a new Mementos request from this, titled Daughter’s Just a Meal Ticket , which you will be doing in a few days. At night, clear the restaurant of any customers, then read Speed Reading at the counter.
Confidant: Choose either "What horrible parents" or "We have to put a stop to this" for the first response, then either "I’ll do it, for you" or "We’ll show them the truth" for the second one.
Start off the day by getting another Affinity Reading for Hifumi, which should be the last now, then get an Empress Persona if you don’t have one. When you visit Haru on the school’s rooftop, you will mention of growing some vegetables. Right now, you have the choice between a Moonlight Carrot (full SP to one ally) or a Sun Tomato (100 SP to the entire party). Pick whichever you want and you will see the date when it will be finished. After doing that, hang out with Haru, noting you need rank 5 in Proficiency in order to do so.
Confidant: Pick either "Are you opening a cafe?" or "Are you starting a farm?" for your first response, then "He sounds suspicious" for the second, and "This is a complex issue" for the final one.
At night, you will finally be able to rank up Hifumi, thanks to all of those Affinity Readings you did.
Confidant: Choose "Give it all you got" for the first answer, then "A very queenly decision" for the second one. If you want to become romantic, pick both "I want to stay by your side" and "I want us to date." If you wish to remain friends, go with either "I want to become stronger" or "We’ll be friends forever."
