Adenine

Adenine (Japanese: シキ, Shiki) is a Rare Blade in Xenoblade Chronicles 2. She can grant tremendous power to her Drivers, Rex, Nia, Zeke or Mòrag, and their allies. Adenine uses the wind element, wields Knuckle Claws, and acts as a Healer in battle.

Adenine was designed by Kōji Ogata.

Personality

Adenine is a scholar, interested in learning and books. She speaks using a wide range of vocabulary. Additionally, she is excited at the prospect of new knowledge; the Tomes of Morytha in particular. She displays an unusual level of excitement at the idea of learning about the past and an ancient tablet. This does not distract her from her duties as a Blade, as she makes it clear that she will fight to the best of her ability when asked to do so. She likes to dance, especially to show her excitement.

Appearance

Adenine has a reedy silhouette, short turquoise hair, teal eyes and holes in her stomach and shines through which green light particles can be seen. She wears a white dress made of paper pages with belt straps and armoured arms. A large book is attached to a brace around her neck, which floats during combat; Adenine fights using Knuckle Claws also resembling books.

Heart-to-heart and Blade Quest

Adenine's Heart-to-heart, "Walking Encyclopedia", takes place in the Argentum Bazaar between Adenine, her Driver and a Nopon customer looking to buy a book that Adenine is also interested in. The two have an argument over who should buy the book and agree that the winner of a test of knowledge should win it. After conversing about either the history of Argentum or Uraya, the Nopon yields and Adenine goes to purchase the book before realising she has no money.

Adenine's Blade Quest, Limits of Awareness, is activated after completing the Merc Missions Tome of Morytha Vol. 1, Vol. 2, Vol. 3 and Vol. 4. In it she expresses an interest in following the information in the tomes to an ancient stone tablet, which contains password-guarded information about another hidden trove of knowledge. This excites Adenine greatly, and once she figures out the password the party join her in heading to the Data Processing Room in the World Tree. This is guarded by a Sovereign, who attacks Adenine, but is defeated. Adenine decrees that the information stored in the room could take centuries to decode, and asks that she be allowed to stay and learn more in her free time.

Etymology

Adenine's Japanese name can be roughly translated as "standard" or "formula" (kanji: 式).

Her English name may come from the nucleobase adenine, a biochemical molecule and component of DNA and RNA which is important to different cellular functions, including energy storage and protein synthesis.

Trivia

After her Blade Quest, Limits of Awareness, is completed, Adenine can be found in the Data Processing Room of the World Tree when not engaged.
