Your goal here is to find the Ring Town Leader Hayate, requesting to become a Ranger youself, and he can be found a bit further north. Once you talk to him though, you will hear screams from Plusle/Minun, and it turns out that it is chased down by a Houndoom. Hayate gives you the Capture Styler to capture Plusle/Minun, after he demonstrates by capturing Houndoom. This should be a relatively easy catch, and afterwards you two set free both pokemon. At this point, you will also be asked your name, and receive the Ranger certificate. When Hayate takes you back to Ring Town, Plusle/Minun will secretly tag along.

Ring Town:
Upon arrival at Ring Town, Plusle/Minun will run away again. You enter the Ranger Base, and Hayate will introduce you to the Rangers there. He will then take you on your trial mission. Trial Mission: Fear No Failure!

In this mission, you need to help the old man Sekine find his lost pokemon in the Lila Forest, which is just to the north of Ring Town. Wander around a bit, and after you capture several Chicoritas and Zigzagoons, a Taillow will appear. You may have a bit of trouble capturing Taillow, but Hayate will voice over to guide you. After you capture Taillow and return it to Sekine, someone will report that some trees are on fire, and Hayate will capture a Mudkip to demo how to use its water field ability. You capture a mudkip yourself to do the same, and this mission to over.

Back to Ring Town, Hayate will tell you and your fellow Ranger to patrol in town for a bit. To the northeast, there is a man named MC Harapper who lets you go on a Field Capture Challenge, but you can't play this at this stage yet.

Walk around, and soon Sekine's Taillow will be causing trouble again. It chases after Plusle/Minun who has followed you there, and after capturing Taillow again, your fellow Ranger will suggest you taking Plusle/Minun as your one permanent pokemon partner, something which all Rangers have. Once that is done, return to the Ranger Base, Hayate will first tell you to go to the second floor to check on his Fearow, after which he will give you the first official mission.

Mission 1: Guard The Professor!

You mission here is to take Professor Shinbara, who is carrying the Super Styler, to Fall City via the Croca Tunnel. Enter the Lila Forest again, and go north. Soon, you will come across a haystack blocking the way. Capture a Torchic to burn it down, and keep going. Soon, you will find yet another pile of obstruction on your way, and a Combusken will conveniently jump out to let you capture. Burn down the obstruction, and you will arrive at the Croca Tunnel.

Croca Tunnel:
At some point, boulders will fall down to separate the professor from you, and you must venture into the interiors of the tunnel to find another way around. Unfortunately, the evil gang in this game, Team Go-Go, will make their appearance here and steal the Super Styler from Shinbara. An obstruction requiring cut will be present, so capture a Paras to take care of the job. Once you reunite with Shinbara, head out from the other end of the tunnel to the East Road, and you will see a rampaging Rhydon.

Capture Rhydon, and you will be ready to enter Fall City. However, at this stage, you are not allowed to carry pokemon away from their natural habitat, so anything you've captured at this point must be released before you can proceed.

Fall City:
Once you arrive at the Ranger Base, talk to the Fall City Leader Joe, and your mission is complete. Your Ranger class will be upgraded to Rank 2, and you are now able to use the Fighting type pokemon assist. While Joe departs with the professor, you talk to the other Rangers there, and Fall City's top Range, Aria, will soon make an appearance to meet you. She will not be too pleased with a foreign Ranger though, but it's nothing you can control.

Joe will return to tell the Fall City Rangers to patrol the city, and you volunteer to join them, which leads you to your second official mission.

Mission 2: Fall City Patrol

Head east from the Ranger Base, and a lady will beckon you to follow her. She leads you to a building on the east, and apparently a box blocks the door to her room. Go out, find a Makuhita, and use its tackle ability to clear the obstruction. The lady enters the room, only to find a Venonat inside which she detests. You capture the Venonat and set it free, and completes your task here.

The next thing you do is help a woman find her 5 lost Skitties. Their locations are:
1) Roof top of the building in the east where you've just been
2) In a house to the northwest of the city, one will be pretending to be a plushie
3) Go south, one will be just around the fountain area
4) Along the market streets, you will see two trash bins, capture a Snubbull to tackle one, and the Skitty hiding inside will jump out
5) From the fountain area, head east, and there is a road sign which blocks a small alley, cut it down with a Meowth, and the last Skitty will be in that small area at the end of the alley. You will see Team Go-Go training with a Machoke as well.

Next, head to Prof. Shinbara's research place, which is to the north of the Ranger Base. His assistant inside will want something to light up the basement, so you head down south towards the harbour, the same one at the beginning of the game, and there will now be a stairs leading down. Previously, this was blocked by a sleeping Snorlax. Go down, capture a Staryu, and head back to Shinbara's assistant to help her lighten up her room.

Finally, the Machoke of Team Go-Go will be causing havoc at the Time Tower at the very north of the city. Aria will also be there, but it is your job to capture the Machoke. This can be a bit tough, so Plusle/Minun's paralyze assist may be useful to halt Machoke for a bit. After that, head back to the Ranger Base, and your second mission is complete. Joe will raise you rank to 3, enabling you to use the Poison and Psychic pokemon assist. Afterwards, you will receive your third mission.
