『ホルス』では、今度は奥山さんが原画で、その下で私が第二原画を担当しました。[...] ブランコに乗っているヒルダの両脇に、チロとトトがやってくるところですかね。

However,The book "太陽の王子　ホルスの大冒険と東映長編まんが映画の世界" says that Yasuji Mori is in charge of the encounter between Horus and Hilda.

This should go

『スーパーアニメーターに無理言って描いてもらったけど本人的には納得してないのかもしれないですけどすごい夕日の中だからBLとか機械の密度感とか画面の強さがあったのでそこから街の中に消えていくエモいところから海、上がりを拝みました』

Saurabh Singh too, he animated the last part of this episode cmiiw

Saurabh Singh, if I'm not mistaken Takeshita and others mentioned about rotoscope too (or maybe they just use a reference video for this scene). They praised Saurabh for pulling this off without a hitch.
