Set in the comfort of your own room, it's an intimate, sleep-ready pampering session.
I Will Lose. series, 24th installment! Also deburi's 29th work, marking our 3rd anniversary!! This time's little brat is the original main-heroine little brat of the I Will Lose. series, 'Shiina Mirai'! Voiced by Nemune Rima!! Your little sister Momo's classmate, Shiina Mirai, has come over to play again! Mirai had promised to cook together with Momo, but Momo forgot to buy the ingredients and rushed out to get them, so the two of them ended up missing each other. You, Momo's older brother, have no choice but to let Mirai into your room and wait for Momo to come back... While chatting, Mirai shows off the apron she brought along for cooking. Mirai, who has a crush on you, bashfully murmurs that it makes her look like a wife. When she hears you say the apron makes her look more like a mom, Mirai finds it amusing and starts playing the part of your mother. "More like a mom than a wife? Eh, really? Ah, but... since you're such a hopeless big brother, maybe being your mom suits me better than being your wife♪" But faced with the bewildering sight of a little brat acting as your "mom," your sanity gradually begins to crumble... Turning your little sister's classmate into your "mom," having her clean your ears, listen to her heartbeat, sleep beside you, and spoiling yourself on her completely—feeling a pang of guilt over the depth of this sin that's surely bound for hell, yet unable to resist her overwhelming, irresistible embrace, humiliated by her gentle little-brat teasing as she digs deep into your ears again and again, surrender and lose as you turn into a total baby.
A little brat who is your little sister Momo's classmate. Within the I Will Lose. series, she is the original little brat and holds the position of main heroine. She often comes to visit you and cleans your ears for you. This time, she has come over to cook together with Momo. She brings along an apron she made in home economics class to show you, but when your sanity crumbles and you end up spoiling yourself on her completely, she's left flustered. Still, skillfully switching between her natural warmth and her little-brat charm, she once again ends up making you lose.

You'll spend a healing time together with "Shiina Mirai," the original OG wife-type bratty girl (mesugaki) from the "Makeru" series, performed by Nemune Rima-san. As an overall impression (highlights), I'll list the following points. 〇 It was great how "Mirai" made you fully feel the "original OG wife-type bratty girl" element 〇 Just when you think you're being teased, she wraps you up with full-blown warmth and spoils you—that balance was exquisite and so healing 〇 Each track is packed with healing elements, so you can fully immerse yourself in the situation If you're interested, please give it a listen. (→ I plan to post a more in-depth review on the DL channel.)
It's here! It's here! The 4th voice work of our beloved Mirai-chan! (Or is it the 5th, counting the double-mesugaki one?) Deburi-san's works have had a lot of aggressive new characters lately, but this time Mirai-chan goes full offensive too! It's a mommy-play explosion of maternal energy! This time, Mirai-chan's first-person pronoun is none other than "Mama"! At first she does the mommy play while feeling a bit embarrassed... but of course, being Mirai-chan! As time passes she gets more and more into it! She's even more affectionate than usual, and in the latter half she talks in "deshimasu" baby-talk speech! The combo of ear cleaning + mommy play was beyond imagination, and the sense of security and comfort brought about an incredible drowsiness... By the way, in her normal state she still calls you "Onii-chan" as usual. When she's really into it, she calls you "boku" or "baby-chan." This way of addressing you is oddly addictive too! Of course the ear cleaning is great, but the final "sleeping together" track is a must-listen too! Even during the sleeping-together part, Mirai-chan in mommy-play mode lets you be more intensely clingy than usual! And on top of the sleeping-together, there's even finger ear cleaning... Deburi-san's finger ear cleaning has become quite standard lately, but this is actually the first time Mirai-chan has done finger ear cleaning for you. This time too, it was addictively pleasant. What's more, she even showed off a series-first technique: "finger ear cleaning while letting you listen to her heartbeat"! It was an extremely satisfying work, fitting to commemorate the 3rd anniversary! Once again, Mirai-chan showed us she's on a different level. The combo of ear cleaning + bratty-girl mommy play! Please, you should experience it too!
It's Mirai-chan, familiar from Deburi-san's "Makeru" bratty-girl series! While keeping a moderate amount of bratty-girl elements, Mirai-chan is likeable to the max from the very start—she's just too cute for words! And this time, on top of that, there's the forbidden "Mama" element... It's invincible! The one and only regrettable point is... The drowsy power generated by Mirai-chan's babying is so strong that I haven't been able to listen to the whole work yet! I've already repeated it about 20 times, but I still haven't managed to listen to the part for the other ear! That's how much I can vouch for its practical effectiveness!
