Okumura and Ririsa stand together on a lively Kamata street near the karaoke building, sharing a light but intimate moment.
This moment takes place while the two are out together, as their relationship shifts from simple club interaction into a shared otaku connection that only they really understand. Okumura becomes especially animated whenever the conversation turns to Liliel, while Ririsa enjoys his completely sincere enthusiasm and also feels happy and slightly embarrassed to be treated with such seriousness. In this instant, the distance between them clearly narrows, giving the scene a light and subtly romantic mood; afterward, the outing further strengthens their bond as fellow fans and partners. The anime’s depiction of the Kamata East Exit area is quite accurate, especially in the scale of the buildings, the direction of the road, and the dense commercial atmosphere around the corner. The location matches Karaoke Big Echo Kamata East Exit Store, and while the anime simplifies some signage and facade color blocks, the place remains highly recognizable. In real life, the signs are usually busier, and nearby storefronts may change over time with different banners or promotions, so some details may differ from the broadcast version. Even so, if you stand near the same street corner and view it from a similar angle, you can still strongly feel how realistically the series used this urban background.
