銀魂―ぎんたま―（Gintama）【46】

お妙が父の遺した道場再興に向けて動き出そうとした折、消息不明だったかつての塾頭と再会。だがSF的な新流派を体得して戻ってきた彼には、地球の存亡に関わる重大な秘密が隠され！？　他にも定春の家出とか。

Oddly trying to move towards rebuilding the dojo that my father left behind, I was reunited with the former cram school who was unknown. However, after acquiring the SF-like new school and returning to him, the serious secret related to the existence of the earth is hidden! Is it? Other than running out of the fixed spring.
