Persona 2: Innocent Sin Walkthrough Part 3 – The Seven Sisters High School
First exit the map you are on. Choose to move to Rengedai. Now head for Sevens (Seven Sisters High School) which is in the middle of the map. When you arrive there a great commotion is going on. The rumor about Sevens seems to be growing as a girl's face is changed.
The source of all this commotion is the fact that the broken clock has started to run again. This causes a lot concern from an old rumor. Ms. Ideal is very concerned as well because of this particular rumor as well. This clock stopped when a teacher died in there defending students. It was rumored that when time started running again time would end.
Head inside and start on your way up toward the top of the school. Your first battle will be against a pair of slimes that offer to explain how to make a Demon Contract. You can use some time to level up your team. Head across to the courtyard and you will see that statue of the Principle is now pacing around the stone. A very amusing scene ensues while you are here.
While inside the school aim to get your team to level 5 and advance your Persona Rank to at least 2. Aim to get your Persona Rank higher. The easiest way to do this is to is through the use of Fusion Spells. If your team is getting low on Health or SP head down to floor 1 and go to the Northwest. This is the Janitor's Room and the lady in here will heal you.
On Floor 2, talk with everyone inside the classrooms. This will open up an optional quest for you to complete later. Talk with them until they mention something about a Ghost named Hanako. Continue to grind up your team. Remember, at least level 5 and Persona Rank 2, preferable much higher. Be sure to experiment and learn more Fusion Spells.
Once your Personas are at least Rank 2, be sure to use these combinations. Order Is Important:
Aqua+Magna+Agi – Tower Inferno
Agi + Magna+Aqua – Hydro Booster
Agi + Straight Slash – Fire Cut Ex
Magna + Straight Slash – Earth Slice Ex
When you have talked with everyone on Floor 2 and are ready, head up to Floor 3. Head to the Northwest where you will find the Principle's Office. Here is another cut scene where you will meet Maya and Yuki. Lisa also gets a new nickname, Ginko. You also get into a cinematic fight introducing the new characters. You are also introduced to the quest to break all the clocks. Take some time to rank up Yukki's and Maya's Persona Ranks, aim for 5. Try to get everyone in the party to level 6.
With these new additions, time for some more Fusion Spells
Agi + Agi – Blazing Burst
Hama + Straight Slash – Light Smasher
Hama + Mudo – Death's Roulette
Dormina + Feral Claw – Stun Claw Ex
On Floor 3 there are two clocks: Classrooms 3-D and 3-B
On Floor 2 there are two clocks: Classrooms 2-B and 2-C
On Floor 1 there are three clocks: Classrooms 1-D, 1-C, 1-A
Now that you have smashed the clocks, before you progress forward, it is time to deal with a side quest that got mentioned earlier. Head for Hirasaka and Kameya Alley, visiting the Detective Agency. Now choose to Spread the rumor about Hanako being seen at Sevens. For 3,000 yen. After that you want to head back to the school. Roam the halls until you encounter Hanako.
Hanako – lvl. 5 Rumor Boss
Your first optional boss battle. If the party is around level 5 you will be fine. Assault with your fusion spells and general attacks. Be sure to stop and heal if needed but likely two or three fusion spells will cinch the battle.
Now head for Floor 2 and visit Classroom 2-B. Give Hanako's Nametag to the Bandaged Male student in the back of the classroom. He will give you 5 Brink Teas. Now head for the Teacher's Lounge on this floor. It is in the Northwest corner of the floor. Walk around the Teacher's Lounge and destroy the three clocks on the walls of this room. There is a brief scene and you have a new objective to make it up to the clocktower. Talk with everyone to learn that the Janitor and the Principle both have keys. Now head down to Floor 1 and the Janitor's room. Talk with everyone in the room and search the box near the door as well as the cabinet above the sink. Once you do another scene will trigger and you get the Clocktower Key.
With the Clocktower Key, it is time to head up to Floor 4. Head up to Floor 3 then go for the center of the floor. You will find the stairwell leading to Floor 4 there. Save before you enter the Clocktower. Inside the clocktower it is time to face the Principle and beat him.
Prinicple Hanya lvl. 7
With a level 6 party this is an easy fight. Use most of your party for Fusion Spells and one person for healing. The Principle will not be toppled by a pair of Fusion Spells so you might have to heal in a later round, just watch your party's HP. He seems to be more susceptible to Fire attacks so use Blazing Burst every round to end the first quickly.
After the battle there is a dialogue choice to be made. Choose “He made it”. This will not come up for a good while in the game but it will. Now head down to Floor 2 and visit Classroom 2-B for an optional scene. After that, clear out of the school and head for the Peace Diner where you will find Kozy.
