Modeus in the semi-official Japanese fan translation kinda gives off imouto chara vibes, and she also has the "tsuiteku" line.

Mmm... I know that Modeus' line in-game is 'You and me. Now.', but what Rice is saying in Japanese is more along the lines of 'Looks like it's just you and me now.' (more literally 'it's become just us two'). It can still be interpreted in a similar way, but it's less full-on perv and more creepy stalker which IMO fits Rice better.

Two years late, but to clarify: Rice's line here is the exact same one used by Modeus in the popular JP translation of the game that most JP streamers use. Just with onii-sama tacked on at the end. I avoid doing recursive translations if the original is known and fits the context.
