Iroi (NTE): Support Role, Banner History and Arc Materials

Iroi is the support half of NTE’s Version 1.2 cycle and one of the fastest-rising searches for the game — she appears as a Breakout term in Google Trends’ three-month related queries for NTE, mostly attached to build and Arc-material questions.

Quick facts

The Support/Survival split is worth flagging honestly: the two public trackers we cross-check disagree on the label, but both agree she is a team-sustaining S-Class rather than a damage carry.

The Lifeline board (closed)

Her exclusive board ran alongside A-Class rate-ups on Haniel, Aurelia and Skia — a useful data point, since that official line settles Skia’s rarity, which community trackers list inconsistently.

Board extras, on the Wayfarer Perks 50 / 120 / 200 milestones:

• “Sheepcopter” glider livery
• “Three’s Company” livery for the B100
• Iroi’s “Archmage” outfit

The matching Arc program was The Wrong Gate, an S-Class Arc available only through that research program during the same window.

Every Iroi outfit

A further outfit was sold through the “999 Nights” Button Shop during that event cycle.

Bond and story content

Version 1.2 phase two added, specifically for Iroi: Bond quests, Bond interactions including the passenger-seat ride-along, text message conversations, a combat tutorial, Random Encounters, a City Hangouts story and a Home Time invitation mode. That is the full support package NTE gives its featured characters — the same list Zankou received in 1.3.

Arc upgrade materials

“Iroi arc upgrade materials” is one of the most common searches attached to her name, and the honest answer is that Hotta Studio has not published an English material reference. What the official notes do confirm is that Version 1.3 streamlined the upgrade flow for Characters, Arcs, Consoles and Modules, and improved the in-game guidance for acquiring Ascension items when you are short — meaning the game itself now points you at the source for each missing material. Use that flow rather than a third-party list that may be a version behind.

General sourcing is covered in the Arcs guide and the modules guide.

Can you still get her?

Not currently — The Lifeline closed on August 19, 2026 with the arrival of Version 1.3, and no rerun is announced. Version 1.3’s supports are the ones on the current boards; until a rerun, the free A-Rank Haniel is the accessible team-buff option, with Sakiri available from the standard pool.
