I added episode 14.5 as the special episode 1. The episodes 外伝第一章・ユストクスの下町潜入大作戦 & 外伝第二章・コリンナ様のお宅訪問 listed as episode 14.5 on official book site, Wikipedia and most streaming sites, which called 第14.5章 外伝第一章・ユストクスの下町潜入大作戦／外伝第二章・コリンナ様のお宅訪問. Please delete the old two episodes that I move to the end at the special season. The streaming start date is 2020/3/10 listed on Wikipedia, which has been deleted on the official site.
