A New Hero Emerges? Walkthrough

Step-by-Step Walkthrough



Speak with Detective Kazama

Detective Kazama World Location

After unlocking New Game Plus and meeting the MAG requirement, head over to the main entrance of Tsukudo-Cho. Look for Detective Kazama standing near the gate.

When you speak to him, he’ll hand you the Bancho Uniform.

Visit Konnou-Ya

With the uniform in hand, make your way to Konnou-Ya. A fairly long cutscene involving Jack Frost will play.

Trigger Combat with Raiho by Calling Him Raihee

Raiho Cutscene
Partway through the cutscene, the transformed Jack Frost will ask Raidou for a good name to call himself. The choice you make here determines whether the battle begins immediately.

To trigger the fight, pick Raihee. Choosing Raiho gets dismissed, while Reiho just makes the poor guy sad. If you need more time to prepare your party, you can intentionally pick one of the other names to delay the encounter.

Unlock Raiho for Fusion After Beating Him

Raiho Unlock

After beating Raiho, he will run away and the Case File will be completed. As a reward, Raidou will receive a Renki and unlock Raiho as a demon that can be fused at the Goumaden!

How to Fuse Raiho: Stats and Skills

How to Beat Raiho

Step-by-Step Walkthrough


Be at Least Level 26

It’s highly recommended to take on this Case File only after reaching Level 26. Hitting this milestone lets you fuse Raiho immediately after the battle, saving yourself from extra level grinding later.

EXP Farming: How to Level Up Fast

Watch Out for Raiho’s Fast Attacks and Summons

Raiho fights fast and closes gaps quickly. He’ll regularly summon groups of Jack Frosts and Jack-o-Lanterns to back him up.

Your first priority should be to break Raiho’s weakness shield as soon as you can. This opens him up for consistent damage and stops his strongest attacks from becoming a problem.

Bring Skills That Counter Jack Frost and Jack-o-Lantern

Since Raiho constantly summons these two, you’ll want demons in your party that can exploit their weaknesses.

Quickly taking down a few of them at a time gives you space to safely focus on Raiho without getting cornered.
