Rappa
Situational—Rappa is an Imaginary Break Erudition. Ultimate “Nindō Supreme: Aishiteru” enters Sealform with an extra turn, Chroma Ink, and a big Break Effect / Break Efficiency spike. Best with Fugue / Ruan Mei / Lingsha / The Dahlia. Super Break AoE; weaker if Break supports are missing. Skip when Firefly already covers your Break and you need another niche.
Rappa is a 5★ Imaginary Erudition Break DPS. Skill “Ninja Strike: Rooted Resolute” is the primary in-combat spend. Ultimate “Nindō Supreme: Aishiteru” is the payoff window for damage or team utility. This Phase 1 page covers kit text, gear targets, and pull notes—team comps stay empty until Phase 2.

Strengths
- Ultimate “Nindō Supreme: Aishiteru” Enters the "Sealform" state—most of the kit’s damage lives inside that window, not on filler Basics.
- Skill “Ninja Strike: Rooted Resolute” hits every enemy on the field in one cast—this is the spend that keeps the rotation honest.
- Talent “Ninja Tech: Endurance Gauge” hits every enemy on the field in one cast—miss the stack conditions and the burst window feels empty.
- Technique “Ninja Dash: By Leaps and Bounds” hits every enemy on the field in one cast—skipping it is free damage left on the table.
Weaknesses
- E0 without “Ninjutsu Inscription: Dazzling Evilbreaker” is still clearable, but the gap versus a signature copy is larger than a single eidolon for most Erudition carries—plan the cone before deep eidolon hunting.
- Rappa wants Break Effect supports and Toughness bars that can actually be broken; into awkward weakness line-ups the Complete Combustion / Break loop loses most of its damage.
- Spamming “Ninja Strike: Rooted Resolute” every turn without watching Skill Points strands the rest of the team—Rappa is often the SP sink.
- If “Nindō Supreme: Aishiteru” is still offline at the end of a MoC cycle, the build is usually Energy/ERR or rotation order—not a missing CRIT roll.
Trace Priority
Nindō Supreme: Aishiteru carries most of the kit’s damage or utility—level this first.
Ninja Tech: Endurance Gauge supports the main rotation—raise after the top priority traces.
Ninja Strike: Rooted Resolute supports the main rotation—raise after the top priority traces.
Ninjutsu: Rise Above Tumbles is last priority outside of filling trace materials.
Stat Priority
Open with Technique if it helps, spend Skill to advance the kit’s resource, and hold Ultimate for the damage or buff window. Exact teammate order lands in Phase 2.
Open supports first, then spend the carry’s Skill/Ult inside the buff window. Exact order varies by the team tab above.
Light Cones
5★ · Path cone
Increases the wearer's Break Effect by 0.6%. When entering battle, immediately regenerates #2[f1] Energy. After the wearer uses Ultimate, obtains "Raiton." After using 2 Basic ATKs, advances the wearer's action by 0.5% and removes "Raiton." After the wearer uses Ultimate, resets "Raiton."
Why it works —Signature / best-in-slot when owned—passive lines up with Rappa’s kit triggers.
5★ · Path cone
For every enemy on the field, increases the wearer's ATK by #2[f1]%, up to 5 stacks. When an enemy is inflicted with Weakness Break, the DMG dealt by the wearer increases by 0.3% for 1 turn.
Why it works —Flexible alternative on the same path—equip if you already own it at higher superimposition.
5★ · Path cone
Increases the wearer's ATK by 0.08%. After using an attack, for each enemy target hit, additionally increases ATK by 0.04%. This effect can stack up to 5 times and last until the next attack. If there are 3 or more enemy targets hit, this unit's SPD increases by 0.08%, lasting for 1 turn(s).
Why it works —Best accessible option for most accounts—raise superimposition when copies drop.
4★ · Path cone
Increases the wearer's DMG by 0.12%. For every enemy defeated by the wearer, the wearer's ATK increases by 0.04%, stacking up to 3 time(s).
Why it works —Budget path cone—fine while building the account.
Relics
Team Compositions
Primary Break / Toughness team for Rappa. Fugue, Ruan Mei, Lingsha are the partners the kit / endgame clears assume first.
Core carry for this shell — owns the damage plan and sets the rotation pace.
Fugue enables Super Break / Toughness pressure rather than a generic CRIT Harmony slot.
Ruan Mei amps Break Effect / action value so Toughness bars die on schedule.
Lingsha keeps Toughness routes alive with heals (and Break-friendly sustain when built that way).
