How do you rescue dex's brother from the kidnapper?

Okay first you go to the square in Electown and talk to the old guy towards the back of it.He gives you a memo. In order to read it look in your key items menu,but you don't need to because I'll tell you what it says "the green navi in town area three" there aren't I nice? Okay back to buisness go to town area three(duh)and look behind the netdealer for the green navi. Have a nice little chat with him and he forks over the hintdata. It says (fixed)the spiral flower vase. Hmmmmmm where is there a spiral vase oh I remember the dendome go through the front entrance and check the middle vase there's nothing there for some reason then you get a mysterious email"park squi" (fixed it means park squirrel) go to ACDC town and check the squirrel your next destination is the place where you fought the one the only Shademan when you get there you find six programs check the two middle ones one of them has a present for you viruses. Well guess what your not done he's hidden five pieces of data across the net and you have to find them by yourself (not).The first one is in ACDC 1 by the skull gate.The second one is in ACDC3 and you better have a thousand zenny ready because thats how much he wants for it the third data is town one (1) answer the question he gives you with the following answers. Personal Terminal, Giraffe, Joman, Nanako, and hotdog. The fourth data is in the lower level of Town 2, you should have a bubbler R ready to trade for the data, if you do not have one you can buy one in ACDC2. The fifth and final data is town 3, and you have to win a net battle against the Heel Navi he only has 100 HP, but has powerful viruses to back him up. And also he has a Area Grab chip. You have all the data now so jack out and return to Electown Square. He sicks a trio of SpikeyEXs once you destroy them Chisao's is free. Run back to the DenDome. And prepare for a match of net battling against Gutsman and Dex.
