In addition to always carrying weapons on you, should also have 3 or more healing items on you. Medicines are the best for HP restoration, but you could just buy some food to carry along with you as well.
Looks like there's finally a lead, but it's a somber one. A corpse of a woman was found in a nearby bay. She had a tattoo of a flower, just like the one on the portrait of Mizuki in the Ares.
This is bad news, but Kazuma spots a single character just below the tattoo, the Japanese character for "Uta." That symbol is a signature of a master tattoo artist, the same one who did the dragon on Kazuma's back. Kazuma decides to pay the artist a visit, and he should be in the Ryujin Building nearby.
Date will wait for you at Serena while you do all the hard work. At the Ryujin Building, Kazuma finds the tattoo artist in good health. Unfortunately, that Uta sign is a forgery; he didn't actually do the tattoo. That kills that line of questioning.
A moment later, the phone rings, and it's Nishiki, who makes vague insinuations about how much he knows. He mentions Mizuki's corpse, which doesn't sit too well with Kazuma, but unfortunately Nishiki doesn't elaborate. Instead, he wants to meet at the Serena later tonight.
Kazuma kills time by getting his dragon tattoo redone, and then it's off to the bar again.
Kazuma updates Date and Reina, and they worry about Haruka's safety. They decide she should go to Purgatory. Haruka isn't an idiot, and demands to know what Kazuma knows, as she's figured out that he left to find something about Mizuki. Kazuma tells her that she needs to relax and trust him, but that doesn't fly. She slams her pendant on the table, then runs away.
What is it with everyone running away from us? At least Date is with us.
If anyone knows anything about anything aside from Kage, it's Aoki. Exit the Serena through the front door and turn north. Get to Theater Square, and talk to Aoki. He spotted her in the nearby arcade, the Club SEDA just north of where you're standing. Two girls in there say they spotted the girl at a parking lot on Shichifuku Street, which is on the far east side of the street.
At the parking lot, an obnoxious jerk will say that the man Haruka was with mentioned something about a part on his cell phone. We know of three: Purgatory, Park #3 (where you found Saya), and a park on the opposite side of the street. For this guide, the man was at Park #3, but it was the third park we checked... maybe he always appears at third park, maybe he moves around randomly. Either way, you may want to check that one first.
A man at Park #3 is on his cell phone, and he leads Kazuma and Date to the Stardust. Men in suits, who do not identify themselves, have Haruka and will exchange her for the pendant. Kazuma tossed the pendant, and as he does so, Date runs forward and grabs Haruka. The jerks fire weapons, and Haruka is hit.
The baddies have the pendants, and they get jumped by other, unarmed guys in suits, triggering a fight. This one gets complex, as not only you have the idiots on the ground to eliminate, but you'll have two shooting at you who as well. Try to take out the shooters first so you won't have to worry about them.
Kazuma tries to interrogate one of the men, but he's killed before anything useful gets out of him. Haruka meanwhile is doing all right; the bullet just grazed her. As she apologizes for running away, Kazuma tells her that Mizuki is dead. Haruka is sad, but accepts it.
Date finds a crest on the man who was being interrogated by Kazuma, so he decides to pursue that lead by himself. Kazuma and Date then take Haruka to Purgatory, where Kage is all too happy to watch over her.
In another scene, we see one of the two suited men who was in the police commissioner's office. His name is Sudo, and was apparently a prot¿g¿ of Date back when Date worked homicide. He and Date have words, but that's all.
You now have a second hideout, this one in Purgatory. Date suggests that Kazuma and Haruka walk the town and have some fun to ease the girl's mind about Mizuki. This probably doesn't include the strip clubs, unfortunately.
On your way out of Purgatory, some bum recommends that you visit the Super Lotto Stand, which is sitting next to the coin lockers. Until now, you haven't been able to do anything there, but who knows? Maybe Haruka is too young to watch strip teases or get plastered, but she's definitely mature enough to gamble!
This is a required thing to do, and you'll need at least 100,000 yen to get in. If you don't have that kind of cash, you may want to run around and do some odd jobs. Once you're inside, you'll play a game called Odds and Evens. Easy enough game: two dice are rolled. You bet and guess whether the total is odd or even. Haruka is always right, so go wild and bet the farm each time.
After about eight wins, the shooter takes a break. Haruka tells Kazuma that she is happy, and further tells you that you should buy stuff for her with your winnings. Kazuma agrees, and the shooter comes back.
This time, Haruka is wrong, so bet low... Kazuma isn't happy, and chucks some people around. As he does so, the dice get ejected, and Haruka notices they're loaded. The shooter calls in some backup, and a fight starts. It's a snap, don't worry.
After the fight, an old dude, the owner of the parlor, appears and apologizes. Kazuma accepts his apologies, and that's that. Kazuma leaves, gets to keep all his points from the winnings, and gets a 100,000 yen as well.
Date calls, and says that it's almost time to meet Nishiki. Kazuma is nothing if not punctual, so drop off Haruka at Purgatory, then head to the Serena.
Inside the Serena, Reina is waiting there for both you and Nishiki. The latter shows up shortly after, and he and our hero drink together.
Nishiki says that Mizuki's death was an accident; he tortured her, yes, but did not intend to kill her. His minions did, and they were both shot on the spot for their mistake.
After that explanation, which sends Reina into a tearful interlude, Nishiki offers a deal. Kazuma gives him Haruka and her pendant, and everything is forgiven and even. Kazuma kindly tells him that's not going to happen, at which point Nishiki reveals he's the one who shot Fuma at Sera's funeral.
Hm, questions are getting answered, it seems. Kazuma punches Nishiki for that. Nishiki does not retaliate, but does say that he'll be doing things "his way" until he's the next Chairman of the Tojo Clan. Kazuma tells him that that's fine; Nishiki can do whatever he wants. But Kazuma still will not give up the girl.
Nishiki declares that they are no longer brothers and leaves. He then summons some guys into the Serena to try to take out Kazuma.
The fight is pretty simple if you've got a weapon or two stocked. Take out the losers, and Kazuma will step outside. Tons more men in suits are there to greet him. Kazuma has no problem taking on the world, and does so.
This second fight is a little tougher, and the main guy (the one in the white suit) dodges most frontal attacks. You'll need to use back kicks and throwing moves to take him down, but he's pretty simple provided you still have weapons. Plus, all the wooden swords the minions leave behind will make nice weapons too, although again you may want to just use grab moves once it's one-on-one.
