2 Friends Who Reincarnated Into Another World.
The flashback?

"This place...tokyo?"

Hakai who is under his subconscious sees the trajectory of his memories in the past.

"Be careful on your right, watch your horses, you're still very slow Hakai."

Hakai heard that voice, emm. instead of hearing it but seeing it, Hakai is currently seeing the moments of the first day he entered the Kurayami family dojo.

Hosh..

Hakai's breath was panting, but his gaze turned towards someone who was none other than Kurayami Hatsuno.

"Heikhhh.., Kurayami sword technique. First move! The steps of the god of lightning!"hatsuno said with his manager

And at once the rock-hard target was split apart with just a wooden sword.

Hakai who was then shown again his memories in the past.

"Kurayami sword flow is a sword flow that uses element techniques, elements that are divided depending on the basis of the user wants to focus on strength, defense, or speed. If you want to focus, you are better suited to using the elements of Fire, Water and darkness. While in defense is more suitable to use the Land, Stone, wind and light. And if the focus is accelerated is none other than the element of Lightning." said the teacher didojo who explained to Hakai who had just entered the dojo.

Hakai was again shown at a time where a student asked the teacher "sir. Can we increase the attack power of the lightning?"ask a student.

The teacher answered "the lightning is divided from the first 4 parts, namely white lightning, the second is yellow lightning, the third is red lightning and the fourth and the last is black lightning."obviously the teacher

Note:

*the white driver is a defensive lightning bolt, which is a fusion between the elements of lightning and light

*the yellow lightning is pure lightning whose speed is doubled

*the red lightning is a lightning strike yes arguably is a lightning merging between the elements of fire and lightning

*black lightning or lightning coming from the sky of chaos, which can scorch everything, where the lightning is a combination of the elements of lightning and darkness.

"Hey... Isn't that Hatsuno?"said Hakai who was looking at Hatsuno from afar.

Note: Hakai sees the current Hatsuno, not the current flashback.

Hatsuno distanced himself from Hakai and said little "keep yourself Hakai. Maybe someday we will meet but in being a mus.." said Hatsuno while disappearing.

Hakai realized, he saw around him it turns out he was awake in Lili's lap.

Hakai was surprised, "why did I wake up in Lili's lap" asked Hakai inwardly.

"E-hhh..." Lili opened her eyes and the replicas screamed out of excitement "Ha-Hakai! You awake yet? You know I'm not worried about you! You've been unconscious for 15 days!"lili said as she hugged Hakai.

Hakai at that time, yeah-well how weh. people suddenly hugged.

Hakai then said to Lili while breaking away from Lili's embrace "Li-Li."

"Huwa" shouted one of the servants at Akio's house. "W-what are you two doing, this is what I have to report to the master" the maid said.

Ziu......

suddenly Akio appears out of nowhere, and when he sees Hakai and Lili hugging, Akio kicks Hakai.

Note: somehow obvious the important Akio is using the Teleport type of space and time magic.

"Akhhhhhh, Bus. buses" cried Hakai while being thrown.

"H-hey! What are you doing, huh? How dare you do such a thing in my house" angry Akio.

"You misunderstood my brother" replied Hakai who was trying to wake up.

Lili spoke up at that time.

"Ma-master Akio. be-begini me who hugged Hakai because I was so excited to see the 15-day-old hakai who was unconscious" explained Lili.

"Be-so? 'Hei Lili your statement of feeling seems very clear woi.' "

inner Akio.

And yet! the tense conversation has just begun! Akio asked Hakai "what happened? how could Hakai use the cursed ancient grade magic."

"Be"
