It's currently the winter season! In turn, Phight tournaments occur less frequently so every Phighter could spend time with their family and friends. Katana, aside from having Hyperlaser as a friend, also has you. In his eyes, you both are platonic acquaintances. Regularly, you and Katana have long conversations at night via video call. Whilst not an active experience, you both enjoyed the comfortable silence. When you had nothing to do, you'd just watch Katana go about his pastime activities. When Katana had nothing to do, he converses with you in deep conversations. All was well...if it weren't for your sensitivity towards the cold. Not like you have a terrible cold that you're bedridden with 10 heaters around you, but even with proper winter clothing, your shivers don't go unnoticed and you have a runny nose from time to time. As such, it's also been a frequent activity that you have tea with Katana in the evening at his apartment. Sometimes, it would even extend to having dinner or even staying over.

Sure, it was unfamiliar territory for Katana to engage in such activities. However, he found himself...enjoying them anyways. One can judge as such from his relaxed stance when you both are spending time together in the comfort of his home and how his voice has a softened edge. All was well.

On one night, you both had a talk about bathhouses. Being ever so curious, you asked him about it.

"Ah, bathhouses are places where people go to relax and unwind. There would be a multitude of them, and the bathwater is always warm. Speaking of which..."

He looks at you in the video call.

"Are you...free, tomorrow?"

You would nod and affirm.

"That is good.. Because I wish to invite you to come to one with me. In these times of winter, especially at its solstice, there is a well known tradition where people go to have 'yuzu baths'. What makes them different is how a peculiar citrus fruit is involved."

He proceeds to tell you about how the Yuzu fruit plays a role in these baths. Yuzu fruits are known for their characteristically strong aroma and the fragrant oil from their skin. They are floated in the hot water of the bath, releasing their aroma. The fruit may also be floated cut in half, allowing the citrus juice to mingle with the bathwater and color it yellow-orange, or enclosed in a cloth bag. Alternatively, yuzu-scented bath salts are used. Yuzu baths are believed to guard against colds, treat the roughness of skin, warm the body, and relax the mind. Interested, you agreed.

The schedule would go like this the next day ; idle free time in the day, tea time and dinner in the evening at his apartment, then you both set out together for a bathhouse of his choice. Excited, are you not? At the current moment, it'll be the tea time segment soon. Come along now, he awaits for you at his apartment.
