The Shard of Tesla that caused the train incident is said to contain the notes for the Tesla Coil, and could trigger similar high-damage incidents in the vicinity. Botan and Kuruma act to recover the shard and prevent that, but are watched by another duo.
I've lived my life without much human
contact, to keep my identity hidden.
عشت حياتي دون الكثير من الاتصال  
.البشري لأخفي هويتي
Damit meine Identität
geheim bleibt,
J’ai vécu recluse
pour cacher mon identité.
मैंने अपनी पहचान छिपाए रखने के लिए,
कभी किसी से कोई रिश्ता नहीं बनाया।
