And little about the roles that Chihiro and Enjoji in history

Let's just say the so called "triangle" hardly even existed. They were both mostly taking their leisure to tease Taichi together during Vol.3 Kako Random and that's about it. After the incident of Kako, Iori started questioning her own feelings towards Taichi and this "triangle in name only" dissolved right away. There were no drama over this particular issue, no arguments nor bitterness, nothing. Only friendly teases. Unless you count the one time during the events of Vol.4 Michi Rand when Iori (Broken) was acting extremely cold on purpose and said spiteful things to hurt Inaba.

Sounds too ideal to be true but I like how it worked out. It's already painful enough to watch them break from Heartseed's trolling anyway.

As for the two newbies' role:

Spoiler for Vol.6 Nise Random:

Chihiro is the primary antagonist and narrator of this volume. While Enjyouji is the second narrator. We see most of the events in this arc through their perspectives.

Heartseed started the 5th trolling phenomenon by giving Chihiro a power of "illusory projection." He spent most of this time trying to sabotage the original CRC members and being a woobie asshole, at least before he realized his mistake and redemption in Nise arc.

Enjyouji on the other hand, spents most of the first half of the arc being "passive" towards the situation, Heartseed actually approached her too but she initially rejected Heartseed's offer before the beginning of the arc. So she had a hunch of what's going on with Chihiro. When things finally gone horribly wrong, her guilt of herself not doing anything eventually drives her to accept Heartseed's offer and she used it to convince Chihiro to confess to the remaining CRC members.

Afterwards it's the standard "fixing" progression. I won't spoil the ending or resolution here but this is basically how the story went.

Some of my thoughts regarding the volume can be found here.

I should also add that, I feel that Chihiro's story in this arc serves as a prologue as well as one of the key factors for what's about to happen to Taichi in the next arc, Vol.7 Yume Random: What would happen if a person, who is at lost of his purpose, is given power?
