Rachnera Arachnera/Relationship

These are the various relationships Rachnera has or had over the series.

Kurusu Kimihito
Rachnera has feelings for Kimihito.

Miia
Much like Centorea, Miia appears to be rather distrustful of Rachnera and acknowledges her as one of her main love rivals. However, Miia does genuinely care about Rachnera as evidenced by her concern in Chapter 27 when Rachnera's original host family seeks to have her returned to their care.

Papi
Notwithstanding Rachnera's frightening appearance and the initial reserve of their other housemates, Papi and Suu have taken a liking in the Arachne ever since she first moved into the household.

The two hold Rachnera in high regard, valuing her knowledge and the time she spends helping them with their studies to the point she has quickly become their favourite “teacher”.

Rachnera also babysits Papi and Suu on occasion, seemingly getting along with their mischief.

Centorea Shianus
Centorea greatly resents Rachnera seeing her as a contender for Kimihito’s attentions. Upon her arrival, she had suddenly become hyper-protective of Kimihito mainly due to Rachnera's previous attempt to kidnap him as well as her distinctive lascivious demeanour, something that would later on culminate in her stating her hate for the Arachne. Nevertheless, Rachnera dismissed her statement with a laughter and some advice on how to be more honest about her feelings.

As the series goes on, Centorea has come to trust Rachnera to some extent, even if still somewhat resentful.

Suu
Notwithstanding Rachnera's frightening appearance and the initial reserve of their other housemates, Suu and Papi have taken a liking in the Arachne ever since she first moved into the household.

The two hold Rachnera in high regard, valuing her knowledge and the time she spends helping them with their studies to the point she has quickly become their favourite “teacher”.

Rachnera also babysits Suu and Papi on occasion, seemingly getting along with their mischief.

Meroune Lorelei
Meroune has always treated Rachnera with ostensible kindness, at times addressing her in a very polite fashion.

When Meroune had apparently been kidnapped by Oct, Rachnera tried to make good use of her abilities in order to come to her rescue.
