+ Talent: Prioritizes attacking ranged enemies.
- S1: relatively weak and poor up-time.
- Kroos is superior in most situations

Operator Overview

“What's wrong with my halo? I don't know why, but it seems to have deviated slightly. According to Dr. Kal'tsit, this is probably linked to my abnormal hippocampus.”

The “genius pretty boy” with the cockeyed halo, Adnachiel has been slow to complete the Laterano Firearms Usage Agreement so he can legally use a gun. He feels more comfortable with his customized crossbow, which he wields as a 3★ Anti-Air Sniper who targets ranged units before other kinds of enemies.

Adnachiel’s kit is simple and straightforward. Once promoted to E1, he gains the Shortcoming Breakthrough Talent, which increases his attack speed and causes him to prioritize ranged targets first, which is a fairly rare targeting priority. If you want to use Adnachiel, be sure to promote him quickly so he gains this ability. His Skill, ATK Up α, increases his ATK for the duration, which is simple but useful.

Unfortunately, despite his status as a “genius,” Adnachiel has some flaws holding him back. As a 3 Operator, Adnachiel can’t E2-promote, limiting his growth potential and his number of Skills. His niche--targeting ranged units--is usually not necessary, 2 Sniper Rangers is a better (and cheaper) choice for anti-air, and 3 Sniper Kroos has better general-purpose DPS. However, if you’re struggling to pick off some annoying ranged enemies—or if you’re just charmed by his quirky visual design—then Adnachiel may be useful to you.

Increase Trust to 50.
Operators familiar with Adnachiel tend to use one word to describe the angel: bright. No matter how complicated the subject or advanced the technology involved, he seems to have no trouble mastering it in a short period of time.
In a show of humility, Adnachiel stands helpless in the face of loftier, theoretical topics, though everyone assumes he's just being modest. After all, as soft spoken and kind as he is, Adnachiel gives off the impression of being a clever and considerate young man. After meeting him, most operators come to understand his observant and sensitive personality. He always speaks to the true nature of things, but the scope of his theories is limited to that over which he has immediate control. Through his analyses, he can even predict the short-term future of his targets. He consistently rejects the titles of both 'prophet' and 'genius pretty boy,' but rumors about him continue to proliferate.

Increase Trust to 100.
When he has free time between missions, Adnachiel often goes to the Rhodes Island Maintenance and Repair Workshop. Working as an intern assistant, Adnachiel's wrists are flexible and his attention to detail is meticulous. He has demonstrated an insatiable curiosity about Rhodes Island's equipment.

Increase Trust to 150.
Adnachiel has not yet completed the Laterano Firearms Usage Agreement. His most trusted piece of equipment is his personally modified crossbow (Laterano crossbows are very different from the metal crossbows mass produced by Raythean). As he is not sufficiently physically strong, Adnachiel's crossbow has a pedal on the front used to help pull back the string with his foot.

Appointed as Assistant That device you're holding seems to be in poor shape. Would you mind if I take a look at it?
Talk 1 Hey, Ansel. Cardigan looks good today. Anything I can help you with?
Talk 2 We have a squad of very interesting people, especially Melantha. She always seems to be hiding from me, but I can sniff her out.
Talk 3 Cardigan, what are you doing? You look so happy.
Talk after Promotion 1 Not every Laterano has the right to use guns, rare weapons that they are. In my hometown, we're pretty good at making knockoff gun parts. The crossbow crafting industry is also on the rise. The result is what I have here - a crossbow with a tactical rail attachment.
Talk after Trust Increase 1 Would you like to try some of my handmade sweets? I'm kind of ashamed that I can only make 25 types of desserts. It feels like I've disgraced the Laterano people.
Talk after Trust Increase 2 What's wrong with my halo? I don't know why, but it seems to have deviated slightly. According to Dr. Kal'tsit, it probably has something to do with my abnormal hippocampus.
Talk after Trust Increase 3 Instead of watching you from afar, I feel much better standing by your side, Doctor.
