Story
A weathered past. A sworn duty to defend home. A dream to blaze a trail across the world— These were entrusted to the unworldly youth by a pair of rough, calloused hands. "Soon, we'll be able to go to a larger world." The boy happily accepted his inheritance. Guarded by youth, he could not yet feel the weight born by the object's significance. "Of course. Before that time comes, however, guard this place well, Misha." He thus engraved that promise deep inside his heart, holding to it forever and always.

How to read this Light Cone page
Every Light Cone has exactly one passive effect tied to the wielder's combat performance; that effect scales up as you Superimpose it from S1 to S5 — use the S1-S5 buttons above to see the exact numbers at each level instead of guessing or interpolating. A Light Cone only delivers its full value on a character who shares its Path; "Characters who use this cone" lists every character on that Path, while "Best users" is a narrower list pulled from real build consensus, not a guess.
Base stats (HP/ATK/DEF) are shown at Lv80 for every cone of the same rarity so they can be compared directly; a 5-star cone will always edge out 4-star and 3-star ones here — the real difference lives in the passive effect, not the flat stats. The "Alternative cones on the same Path" section suggests a few other options if you do not own the signature cone yet, or want to compare before spending ascension materials.
