Is there a hero among us who can translate what they're saying in these scenes?
For the first episode, Leifang is taking a breather from setting up the most recent festival (presumably referring to the first anniversary). Misaki then comes over to thank her, with Leifang congratulating her, shocking Misaki, admitting she did not expect to get congratulated by Leifang. She also admits she has some confidence issues and wishes she had Leifang's confidence. Leifang then offers to meet up tomorrow at her room. Presumably the next day, Misaki arrives and is shocked to see Leifang in a very revealing outfit, with Leifang forcibly changing Misaki into a similar outfit (hence why she seemed to grope Misaki), with Misaki commenting on her butt being exposed. Leifang then explains the outfits were for training under Jikiden's "beautiful legs" thing, though Misaki's unsure due to the exposed butt, before Leifang clairifies that under that philosophy, the hips and waist also count as part of the leg training before telling her they shall continue training due to being convinced, much to Misaki's hesitance.
The second episode has Leifang guiding Misaki via various poses, also suggesting to Misaki to firm up her rear end a bit before getting to the final exercise, with Misaki taking Leifang's advice to enjoy herself. Afterwards, Leifang congratulates Misaki on a job well done, with Misaki also admitting that she is at least starting to gain some self-confidence, even if a little, though she does wonder whether Leifang actually wears this for every exercise. Leifang, taken aback by this question, then lets slip that the outfit was actually Tamaki's idea were Leifang to teach Misaki how to get self-confidence and that she promised to pass on a video of this training, much to Misaki's chagrin.
At least, that's what I got out of it from Bing translator. You can find the results here:
