That "Old Photograph" you got in the tutorial? Do not sell it for 10 gold. It is a key item required to unlock the "Childhood Promise" CG in Chapter 8.

Shinobi Girl requires an online verification check for the gallery. If you earn an achievement while offline, the gallery mode might not register it, forcing you to re-do the boss fight. The Lore Hidden in the Gallery (Spoiler Warning) Let’s talk about the narrative implications of the Gallery Mode. If you arrange the CGs by ID number rather than chronology, a disturbing pattern emerges.

In the vibrant world of mobile and indie gaming, few genres capture the imagination quite like the ninja fantasy. Among the recent wave of side-scrolling action games and gacha RPGs, Shinobi Girl has carved out a loyal fanbase. While the fluid combat and character progression systems are the main draw, there is one feature that dedicated players obsess over more than any other: Shinobi Girl Gallery Mode .

Most players unlock CGs in order: 1, 2, 3, 4... However, the Databook entries in the gallery suggest that the "Shinobi Girl" we play as—Rin—is actually a clone. The Gallery Mode contains "Mistake" images: blurred photographs, broken mirrors, and identical characters standing in the same room.

If you are a casual player who just wants to beat the final boss, ignore the gallery. It will add 20-30 hours of grind to a 10-hour campaign.
