Persona 2: Innocent Sin Walkthrough Part 6 – Kasugayama High School

Welcome to Kasugayama  “Cuss” High School, rival to Sevens, and Michel's school. Michel will have rejoined the party so it is time to level him up some. There are also new fusion spells for you to learn as well:
Wind Slash EX: Straight Slash + Garu
Kamaitachi: Aqua + Magna + Garu

Target Party Level: 10
Persona Ranks: Pixie, Poltergeist rank 8

To get all the fusion spells, likely you will need to visit the nearby Velvet Room simply to rotate out a persona or two. Your first destination for the school is up on Floor 2. Still, take some time to talk with everyone and explore the rooms you can on Floor 1. If you exit through the Northwest you will find yourself just outside the Gym. There you will find the School Nurse who will heal your party for free! Great as there is Persona Rank Grinding and Level Grinding to do.

When you want a change in scenery head up to Floor 2. Talk with everyone to learn more about what has been happening. You next real stop is in the Western part of Floor 2, the Student Coucil Room. There you will hear mentions about an Exchange Student who is no longer around. You will also start to hear about the Student Council President having gone down to the basement. Be sure to talk with everyone in the room. If you forget, be sure to stop into any classroom down on Floor 1 and they will talk about it as well. Head back down to Floor 1 and go for the downward stairs in the Southwestern corner of the floor.

The basement is a very small area to be navigating. Simply head for the one door that is southwest of the stairs. Inside will be a scene where Ginko and Michel both run into the next area together. The rest follow just after them ... into the Bomb Shelter which is rumored to not have an exit.
