There are two types of spells:
- Tactics (戦術, senjutsu) to control Yaya's magical circuit, "Herculean Strength" (金剛力, kongouriki)
- Absolute skills (絶衝, zesshou) based on the tactic
Tactics
The spell is Pattern (magical nature) + Number (magical power) + Formation
There are 4 patterns which are comparable to Fuurinkazan:
- 吹鳴 (suimei, blowing [a whistle]) / whistle: increase the agility/speed, "as swift as wind"
- 森閑 (shinkan, stillness): strengthen the defense, "as gentle as forest"
- 光焔 (kouen, light & flame) / flare: increase the number of attacks/power, "as fierce as fire"
- 天嶮 (tenken, natural defenses) / stronghold: increase the attack power/durability, "as unshakable as mountain"
(However, according to an interview on Monthly Comic Alive 2012-9 with Reiji Kaito, the author of the series, he mentioned that suimei is for speed, shinkan is preserving magical power with things that aim for counters, kouen is for both speed and attack, and tenken is for defense)
The number represents the power. The higher the number, the more powerful it affects. As for now, it seems the number is always a multiple of 12 with the highest being 48.
The formation is separated into 2 types:
- 衝 (shou, thrust): Yaya attacks independently
- 結 (ketsu, bind): Yaya attacks first on a cooperative attack
Some examples:
- 吹鳴二四衝: 吹鳴 (suimei) + 二四 (ni-jyuu-yon, 24) + 衝 (shou)
- 光焔十二結: 光焔 (kouen) + 十二 (jyuu-ni, 12) + 結 (ketsu)
Skill
The spell is Pattern (magical nature) + "Absolute" (絶衝, zesshou) + Name
The pattern follows the previously mentioned pattern.
The name is just a proper noun.
The skills from the first 4 volumes corresponding to each pattern are:
- 天嶮絶衝<破却水月>: 天嶮 (tenken) + 絶衝 (zesshou) + 破却水月 (hakyaku suigetsu, destruction of the moon reflected on the water) / Final Stronghold "Razing Moon Reflection": By striking a blow against an opponent in a hardened state, Yaya can interfere with the opponent's magic and cause it to lose control.
- 吹鳴絶衝<ひさぎ太刀影【たちかげ】>: 吹鳴 (suimei) + 絶衝 (zesshou) + ひさぎ太刀影 (hisagi tachikage, silhouette of Catalpa long sword): By sending several ten times of the magical power, Yaya jumps to the air in a flash, almost looks like disappearing.
- 光焔絶衝<乱れ夜桜>: 光焔 (kouen) + 絶衝 (zesshou) + 乱れ夜桜 (midare yozakura, disturbance of cherry trees at evening): By sending out the magical power to the whole body, Yaya does a super rush attack by punching & kicking relentlessly while in that state. Even if each attack may be light, the attack rush can be continued while maintaining the magical power.
- 森閑絶衝<神機御雷【しんきみかづち】>: 森閑 (shinkan) + 絶衝 (zesshou) + 神機御雷 (shinki mikazuchi, miraculous thunder): Attack the downed opponent by hitting using the fist in the manner of tile splitting. A single blow that has enough power to sink the opponent's body to the ground by as much as 10 meters.
However, the 8th volume introduced 光焔絶衝<月影紅蓮> (kouen zesshou tsukikage guren, moonlight crimson lotus flower) and thus, there's a high possibility that other skills also exist.
(by the way, the previous skill does a reddish, intense rotation kick that can cause burning due to the air friction.)
Note from Nico Nico Pedia: the original source (light novel) itself doesn't explain the detail for both the tactics and skills and thus, it can only be interpreted by the reader/viewer from the given evidence.
