The No. 13 Shard of Tesla had been stolen from Botan and the others, and Jingo believes that the secret organization A Small House was behind the theft. Returning to Japan, Botan, Kuruma and Ryunosuke hope to locate the Shards from their shared dwelling.
At the very least,
I put locks on the crystals
على الأقل، وضعت أقفالاً 
على الكريستالات
Ich habe die Kristalle mit einer Sperre versehen,
die mindestens hundert Jahre halten sollte.
Pero puse un cierre en los cristales
J’ai installé un verrou empêchant
leur utilisation pendant cent ans.
पर मैंने क्रिस्टलों को लॉक कर दिया है
Pelo menos, coloquei travas nos cristais
