When Masamune investigates the abandoned, possibly haunted house next door, he’s surprised to find Yamada Elf has just moved in: and likes to play the piano naked after a shower to get inspired to write.
After the standard accusations of peeping tommery, she invites him in, and most of the episode is given over to making Elf a little more dimensional, if still grating in her intense, obnoxious arrogance.
As Sagiri’s bedroom window faces Elf’s office, you’d think it wouldn’t be long before she found out who Eromanga-sensei is, but Elf sees Masamune’s sister and thinks she’s just that: a little sister who has fun drawing, not the person whose services they’re fighting over.
It’s also a bit shitty of Masamune not to even mention to Sagiri his little wager with Elf, considering Sagiri is the ‘prize’. Then again, it’s a good thing that Masamune isn’t the perfect MC while everyone around him is flawed in some way.
Indeed, Masamune’s flaw seems to be that in spite of Elf’s toxic personality, incessant pretentiousness, and pronunciation of ahhh-neee-may, he can’t help spending time with his new neighbor, nor indeed being a fan himself, even if meeting Yamada-sensei wasn’t what he expected.
For a time, it doesn’t seem like Elf invited Masamune in just to rub his nose in her superior success, but to spend time with a fellow author. She earnestly asks why he’s a fan, and he earnestly answers: after a death in the family, her books cheered him up. They taught him that novels can “save lives” of some readers, and for that she has his heartfelt thanks, competition or no.
Elf’s reaction betrays a softer, more genuine side to her, even if it’s short-lived and she’s back to being awful the next day. But it’s also clear that she’d rather have Masamune around than not, and also strongly disagrees with his workaholic approach to authoring, as she considers her job a “hobby” and only writes if her motivation is maxed out.
Despite knowing nothing of their competition involving her, Sagiri is uneasy anyway because her big brother, who has been All Hers up to this point, is suddenly ‘in the web’ of a cute, rich next-door neighbor.
While her music and online fans keep Eromanga merry, I feel one of the factors that drives her motivation to draw is knowing Masamune will always be there in the house, serving her meals and protecting her.
Yamada throws a thorn in that arrangement, and it will be interesting to see whether that motivates Sagiri to explore beyond her room. But yeah…Masamune really should tell her about his wager with Elf.
