The Rpgmaker system is based on events that usually work by collision or map blocks. unity3d works "free" so the link you provided is just a system rpg semi-ready, you don’t need "something ready" (unless you want to make the job easier), what you need is to study the events that already exist in Unity3d, such as Collider.
Collider
In case you should use the events as:
OnCollisionEnter
is called when a Core/rigidbody starts playing another Core/rigidbody.
OnCollisionExit
It is called when a Colisor/rigidbody stopped touching another rigidbody / Colisor.
OnCollisionStay
it is called once per frame for each Colisor/rigidbody that is touching rigidbody/Colisor.
OnTriggerEnter
is called when the other Collider enters the "Trigger".
OnTriggerExit
is called when the other Collider stopped playing what fires the "Trigger".
OnTriggerStay
is called one by "frame" for each other collider that is playing on "Trigger".
According to @Nils' comment to make the character move from one point to another, display talking balloons, make the camera move, he will need to program/configure this and a good solution is to use the Animation
unity Ctrl + 6 (Cmd/Command + 6 on the Mac)

Note: Trigger refers to the object that fires the event.
Note: If there is any error in the translation do not fail to inform, thank you
Use the triggers of William’s answer below, and to make the moves, dialog boxes, move position camera use the Unity Animator. I explain him better in this video. https://www.youtube.com/watch?v=lCExJKOsSW8&list=PLa2bQ5uCFWA1RNqmaQIAWiq5HiWUGATyC The speech balloons I explain in another video of this same series.

Good afternoon, @Guilhermenascimento. Yes, Collider and Animation totally cleared my doubt, although I still continue to study them for the best ways of use. Thank you, and I’m sorry I missed you earlier.

In addition to the great tips you’ve already been given (and the great @Nils tutorial), if your game is narrative-focused you can take a look at this free add-on for Unity3d called Fungus. The tool greatly facilitates the creation of dialogues between characters and the player, and has very cool features to make cutscenes.
