The V-JUMP Magazine has posted the reference arts used for Raye and Roze for the upcoming anime, The Chronicles:

“A story of a girl that enters into the battlefield, wishing for peace”
From their debut in the pack sold on February 2018, their story has been told in this magazine and across other publications.
There will be plenty of prominent scenes to be animated like the buffing through armaments, each Link Monster and the “Sky Striker Maneuvers”.
A fitting story to be introduced as the top batter.

Necktie: “Necktie pattern”
Sky Striker Ace – Raye
Designs modified for the anime!

The secret reference art illustrations are revealed!!
Sky Striker Ace – Roze
Top right: “Gloves”
Top middle: “Innerwear: shorts and tights”
Bottom left: “Side view”

TL note #1: The greenish note in the middle is unreadable due to the contrast. It is likely that it says “敵国マーク” (emblem of the enemy nation), much like the reference art for Roze in the Card Game Artworks book.

TL note #2: The note on Roze’s hat mentions that the crest is drawn using color tracing, but the context is somewhat vague: In terms of storytelling, a “引き” is a “hook” at the end of the page to make the reader interested in the next page, next chapter, etc. This “hook” could be referring to the teaser where Raye and Roze are fighting.
